Sports Betting Glossary

Action Industry Slang

Any wager placed. "Where's the action?" asks where the money is flowing. "Take action" means place a bet. Books refer to recreational customers as "action bettors."

Action Bettor Industry Slang

A bettor who values having a bet on any game more than finding the best price. Action bettors are recreational by nature, place bets every day, and rarely line shop. Books love action bettors.

Alternate Spread Markets & Lines

A spread offered at a different number than the main line with adjusted juice. Buying a half-point (moving from -3 to -2.5) costs more juice. Selling points (moving from -3 to -4.5) reduces the cost. Use the half-point calculator to evaluate.

See also: /calculators/half-point/

Alternate Total Markets & Lines

A totals line offered at a different number with adjusted juice. Move the over down or the under up to gain probability; move it the other way to gain payout. Common across NFL, NBA, and MLB at every Tennessee sportsbook.

Anytime Touchdown Scorer Markets & Lines

A football prop that pays if the named player scores at least one touchdown at any point in the game. Multi-TD scorer is a separate longer-odds market. Available on every NFL player at every TN sportsbook.

Arbitrage (Arb) Strategy & Math

Betting all outcomes of a market across different books to guarantee a small profit regardless of result. Requires line shopping to find opportunities where the no-vig combined probability is under 100%. Most TN books actively limit confirmed arbers.

Asian Handicap Markets & Lines

A soccer market that eliminates the draw by assigning a fractional handicap to one team. Quarter-goal handicaps (e.g., -0.25) split the stake between two adjacent handicaps. Most extensively offered at bet365 in Tennessee.

Backdoor Cover Strategy & Math

A late-game scoring play by the trailing team that flips a spread or total in their favor without changing the actual outcome. Common source of bad beats. Often comes from garbage-time touchdowns in blowouts.

Bad Beat Strategy & Math

A wager that loses in unlikely or excruciating fashion (a late backdoor cover, a meaningless touchdown, a missed extra point on the over). Mathematically irrelevant but emotionally significant.

Bankroll Money, Odds & Vig

The total amount of money set aside specifically for betting. Separating bankroll from living expenses is the first rule of responsible gambling. Unit sizing (typically 1 to 2% of bankroll per bet) protects against drawdowns.

See also: /calculators/kelly-criterion/

Bet Confirmation Sportsbook Operations

The screen displayed after submitting a wager that shows the actual accepted odds, stake, and potential payout. Always verify that the confirmed odds match what you saw on the bet slip, as lines occasionally move between selection and submission.

Bet Limit Sportsbook Operations

A user-set or book-imposed cap on bet size, deposit amount, or session time. User-set limits are responsible-gaming tools available in account settings. Book-imposed limits are based on the account's risk profile.

Bet Slip Money, Odds & Vig

The interface element where selected bets accumulate before placement. Most TN apps support straight bets, parlays, and Same Game Parlays from a single bet slip. The slip displays total stake, payout, and combined odds.

Bonus Bet Money, Odds & Vig

A promotional credit that returns only net winnings, not the stake. A $100 bonus bet at +100 pays $100, not $200. Cash-equivalent value is typically 60 to 80% of face value, depending on the odds used.

See also: /calculators/bonus-bet/

Both Teams to Score (BTTS) Markets & Lines

A soccer wager that pays if both teams score at least one goal. Independent of the final result. Available alongside match result markets at TN sportsbooks that offer soccer (bet365, FanDuel, DraftKings).

Capper (Handicapper) Industry Slang

A person who analyzes games and produces betting picks, either professionally or as a hobby. Differs from tout in that capper is descriptive (anyone who handicaps) while tout implies selling picks.

Cash Out Money, Odds & Vig

A feature that lets you settle a wager before it concludes for a fixed return based on the current state. The book includes a 5 to 10% margin in the cash-out price. Bet365 has the most extensive cash-out menu in Tennessee.

Chalk Bet Type Basics

Slang for a heavily favored team or outcome. "Betting the chalk" means backing the favorite. Chalk parlays (only favorites) are popular with casual bettors but produce low payouts.

Closing Line Value (CLV) Strategy & Math

The difference between the price you bet and the line's closing number. Consistently beating the closing line is the strongest signal of long-term betting skill, since closing lines are the market's most accurate estimate.

Contrarian Betting Strategy & Math

A strategy of betting against the public majority, on the theory that books shade lines toward popular sides. Most effective on heavily-bet games (Monday Night Football, prime-time NBA) where public bias creates value on the unpopular side.

Debit Card Restriction Tennessee-Specific

Tennessee's law prohibiting credit card deposits for sports betting at every licensed operator. Designed to prevent gambling-related debt. Accepted methods include debit card, online bank transfer (ACH), PayPal, Apple Pay, VIP Preferred, and PayNearMe.

Deposit Match Money, Odds & Vig

A welcome offer structure where the book matches a percentage of your first deposit (often 100% up to a cap). Typically credited as bonus bets with rollover requirements, not as withdrawable cash.

Dog Industry Slang

Shorthand for underdog. "Big dog" refers to a heavy underdog (+250 or longer). "Dog plus the points" means the underdog covering the spread.

Draw No Bet Markets & Lines

A soccer market that refunds your stake if the game ends in a draw. Effectively converts a three-way line into two-way with lower odds. Useful when you have a winner pick but want to insure against the draw.

Edge Strategy & Math

The difference between your estimated win probability and the book's implied probability. A 55% true probability bet priced at -110 (52.4% implied) has 2.6% edge. Without edge, betting is negative EV due to juice.

Expected Value (EV) Strategy & Math

The average profit per bet at a given price, calculated as (win probability × profit) minus (loss probability × stake). Positive EV indicates a long-term profitable bet, assuming probability estimates are accurate.

See also: /calculators/expected-value/

Favorite Bet Type Basics

The team or outcome priced with negative moneyline odds, indicating greater than 50% implied probability. Heavy favorites (-300 or shorter) carry low risk but small returns.

First Half Markets & Lines

A bet that settles on the score at halftime instead of the final whistle. Spreads, totals, and moneylines are all available as first-half markets. Useful when team scripts (early aggression vs late conservatism) differ from full-game tendencies.

First Touchdown Scorer Markets & Lines

A football prop that pays only if the named player scores the very first touchdown of the game. Long odds even on featured running backs and receivers, because of the volume of eligible scorers.

Free Bet Money, Odds & Vig

Synonym for bonus bet at many sportsbooks. Some operators use "free bet" specifically for unrestricted bonus credit; others reserve it for stake-back insurance promos. Always check the specific T&Cs.

Futures Bet Type Basics

A long-term wager on a season-long outcome: Super Bowl winner, MVP, NBA championship, regular-season win totals. Stakes are locked until the event resolves, sometimes weeks or months later.

GeoComply Sportsbook Operations

The third-party geolocation vendor used by most US sportsbooks, including all ten in Tennessee. The GeoComply plugin runs on your device to confirm location for each bet. Failed checks usually resolve with a one-tap re-verification.

Geofence Tennessee-Specific

The digital boundary used by Tennessee's licensed sportsbooks to confirm players are inside state lines. Built from GeoComply technology, the geofence is well configured statewide, including major venues like Nissan Stadium, Bridgestone Arena, and FedEx Forum.

Geolocation Sportsbook Operations

The mobile app technology that confirms you are physically inside Tennessee state lines before allowing a bet. Tennessee's geofence is well-configured statewide; crossing into Kentucky, Mississippi, Alabama, or other states blocks wagers immediately.

Graded Bet Sportsbook Operations

A bet that has been settled by the sportsbook and either credited (won) or debited (lost). Grading delays can occur for prop bets that depend on stat corrections from official league data.

Handle Money, Odds & Vig

The total dollar amount wagered at a sportsbook over a defined period. Tennessee tax is based on handle (1.85%) rather than revenue, making TN the only state with this structure. SWC publishes monthly handle reports.

Handle Tax (1.85%) Tennessee-Specific

Tennessee's sports betting tax structure, unique in the US: 1.85% of total wagers (handle), not of operator revenue. Effective since July 2023, replacing the original 20% revenue tax with a 10% minimum hold requirement. Tax revenue funds education and responsible gambling programs.

Hedging Strategy & Math

Betting the opposing side of an open ticket to lock in profit or cap loss. Common on long-running futures (your team makes the Super Bowl) or live in-game positions. Use the hedge calculator to find the exact stake.

See also: /calculators/hedge/

Hold Money, Odds & Vig

The percentage of total wagered that the book keeps as profit, averaged across many bets. Standard -110/-110 markets have ~4.5% hold. Player props can run 8 to 15%. Same Game Parlays often exceed 10%.

Hook Bet Type Basics

A half-point added to a whole-number line. A spread of -7.5 instead of -7 is said to "have the hook." Hooks turn potential pushes into wins or losses, making them especially valuable around NFL key numbers like 3, 7, and 10.

See also: /calculators/half-point/

Inning Bet Markets & Lines

A baseball wager on a single inning (most often the first). First inning over/under 0.5 runs is one of the most-bet inning markets across TN sportsbooks during MLB season.

Juice (Vig) Money, Odds & Vig

The margin sportsbooks build into both sides of a market. Standard -110 spreads carry 4.5% effective house edge. The juice is the book's revenue and the reason long-term winning requires beating ~52.4% on -110 markets.

See also: /calculators/no-vig-fair-odds/

Kelly Criterion Strategy & Math

A formula for optimal bet sizing given your edge. Full Kelly stakes a fraction of bankroll equal to (bp - q) / b, where b is decimal odds minus 1, p is your win probability, q is 1 minus p. Most bettors use Half or Quarter Kelly to reduce variance.

See also: /calculators/kelly-criterion/

KYC (Know Your Customer) Sportsbook Operations

Identity verification required before withdrawal. TN books verify name, DOB, address, and last four of SSN against public records. Verification usually completes within minutes but can take 24 to 48 hours.

Lay Points Industry Slang

Betting on the favorite and giving up the point spread. "Laying 7" means backing a team at -7. Distinct from "laying juice," which refers to paying the vig premium on a heavy moneyline favorite.

Limit Industry Slang

The maximum amount a sportsbook will accept on a single bet. Limits vary by market type (NFL spread limits are higher than props), by book, and by account. Sharp accounts often face lower limits than recreational accounts.

Line Shopping Strategy & Math

Comparing odds across multiple sportsbooks before placing a bet to capture the best price. Holding accounts at three or more TN books (DraftKings, FanDuel, BetMGM, Caesars, bet365) is the easiest way to line shop.

Live Betting (In-Game) Bet Type Basics

Wagering after the event has started. Lines move in real time based on score, time remaining, and momentum. Available on every major sport at all ten Tennessee sportsbooks, with bet365 offering the fastest refresh.

See also: /guides/live-betting/

Lock Industry Slang

A bet someone is overconfident about. "It's a lock" usually predicts that the bet will lose in colorful fashion. Used heavily by touts and rarely by sharp bettors.

Middle (Middling) Strategy & Math

Betting both sides of the same market at different lines, hoping the final result lands between them so both sides win. Example: Titans -3 at one book and Titans +4 at another; if Titans win by exactly 4, you win both bets.

Mobile-Only Market Tennessee-Specific

Tennessee's unique structure as the only US state with no retail sportsbooks, no casino sportsbook counters, and no betting kiosks. All ten licensed operators run online-only via mobile app or desktop browser.

Moneyline Bet Type Basics

A bet on which team wins outright, with no spread. Favorites carry minus odds (-150 means a $150 stake wins $100), underdogs carry plus odds (+130 means $100 stake wins $130). The simplest market type and the default for hockey, baseball, soccer, and tight football games.

NCAA Player Prop Ban Tennessee-Specific

The SWC rule prohibiting all player prop bets on NCAA athletes in any sport, in-state or out-of-state. Implemented in 2023 to protect college athletes from prop-driven harassment. Team markets, spreads, totals, and futures on NCAA games remain available.

Net Win Money, Odds & Vig

Total profit after subtracting the stake from the payout. A $100 bet at +200 has net win of $200. Bonus bets pay out as net winnings only because the bonus stake is not returned.

See also: /calculators/bonus-bet/

Off the Board (OTB) Industry Slang

A game taken off the betting menu, typically due to injury news (key player questionable) or other uncertainty. Books reopen the market once the situation clarifies.

Open Bet Sportsbook Operations

A bet that has not yet been settled. Visible in the My Bets or Open Bets tab on every TN app. Live and in-game bets remain open until the game concludes.

Parlay Bet Type Basics

A combination of two or more bets into a single ticket. All legs must win for the parlay to cash. Parlay odds equal the product of each leg's decimal odds. Books charge higher effective hold on parlays than on straight bets.

See also: /guides/parlays/, /calculators/parlay/

Payout Money, Odds & Vig

The total amount returned on a winning wager, including original stake. A $100 bet at +200 has payout $300 ($200 profit + $100 stake). Net payout excludes stake and equals profit only.

Pending Bet Sportsbook Operations

A bet awaiting confirmation, typically because the book is reviewing odds movement between selection and submission. Pending bets resolve within seconds as either accepted at the original price, accepted at a new price (with confirmation), or rejected.

Period Bet Markets & Lines

A hockey-specific bet on a single period (typically the first period). Goals scored, who wins the period, and totals are all common period markets at TN books.

Pick'em (PK) Bet Type Basics

A game with no spread because the teams are evenly matched. The bet pays out as a straight moneyline pick. Common in tight NFL Sunday matchups and college basketball mid-season conference play.

Point Spread Bet Type Basics

The number of points a favorite must win by (or an underdog can lose by) for the bet to cover. A Titans -3.5 line requires Tennessee to win by 4+. Standard juice is -110 each way, meaning a $110 stake returns $100 profit on a win.

See also: /guides/spread/

Prop Bet Bet Type Basics

A wager on a specific outcome inside a game that does not directly relate to the final score. Player props (passing yards, rebounds, anytime scorer) and team props (first to score, race to X points) are the most common types.

See also: /guides/props/

Public Betting Strategy & Math

The aggregate action of recreational bettors, typically biased toward favorites, overs, and well-known teams. Public betting percentages are tracked by data services and used as a contrarian signal by sharp bettors.

Puck Line Markets & Lines

The hockey equivalent of a point spread, almost always 1.5 goals. Favorites carry plus money on puck lines because empty-net goals push outcomes. The Predators -1.5 is a common puck line offered at every TN book.

Push Bet Type Basics

A bet that lands exactly on the line (Titans -3 when they win by 3 points). The wager voids and your stake is returned. Half-point lines (-3.5) cannot push.

Quarter Bet Markets & Lines

A bet settled on the result of a single quarter. Available for NFL, NBA, and college basketball at every TN sportsbook. First quarter lines move with opening drive expectations.

Reverse Line Movement (RLM) Industry Slang

When a line moves opposite to the public betting percentage. If 75% of bets are on Team A but the line moves toward Team B, sharps are likely loading Team B with larger stakes than the public is betting Team A.

Reverse Withdrawal Window Sportsbook Operations

The grace period during which a requested withdrawal can be canceled and the funds returned to the betting balance. Tennessee books typically offer 12 to 48 hours. Disabling reverse withdrawal helps bettors who chase losses with pending withdrawals.

Rollover (Playthrough) Money, Odds & Vig

A wagering requirement that must be met before bonus funds become withdrawable. A 5x rollover on a $100 bonus requires $500 in qualifying wagers. Most TN welcome offers credit bonus bets without rollover, but reload promos may have it.

Run Line Markets & Lines

The baseball equivalent of a point spread, almost always set at 1.5 runs. The favorite must win by 2 or more runs to cover. Plus juice often appears on the favorite because road favorites do not bat in the 9th when leading.

Same Game Parlay (SGP) Bet Type Basics

A parlay built from multiple bets within a single game. Books use correlation-aware pricing rather than independent leg multiplication. SGP hold is typically 8 to 15% vs ~4.5% on a straight bet.

See also: /guides/same-game-parlays/

Second Half Markets & Lines

A bet settled on second-half scoring only, ignoring the first-half result. Lines reopen at halftime, often offering value when one side overreacts to early-game flow.

Self-Exclusion Sportsbook Operations

A voluntary process to block yourself from a sportsbook for a set period (often 6 months, 1 year, or 5 years). Tennessee maintains a state-wide self-exclusion list through the SWC that applies across all licensed operators.

Settled Bet Sportsbook Operations

A bet that has been graded as won, lost, pushed, or voided. Settled bets move from the Open Bets tab to the Bet History tab in TN apps.

Sharp / Sharp Bettor Strategy & Math

A skilled bettor who consistently identifies positive EV markets and beats the closing line. Sharps are tracked by sportsbooks; their accounts may be limited or restricted at recreational books that target square action.

Sharp Hold Money, Odds & Vig

The tight hold percentage charged by sharper sportsbooks. Reduced-juice books offer -107 instead of -110, lowering theoretical hold from ~4.5% to ~3.3%. Less common at major US books but occasionally appears as a promotion.

Sharp Money Industry Slang

Action from professional or skilled bettors who consistently identify edge. Sharp money tends to come in large stakes from known accounts, and books often reprice quickly to absorb it.

Sports Wagering Council (SWC) Tennessee-Specific

The Tennessee state agency that regulates sports betting. Took over from the Tennessee Education Lottery Corporation (TELC) on January 1, 2022. The SWC licenses operators, enforces rules, publishes monthly handle reports, and operates the state self-exclusion program.

Square / Square Bettor Strategy & Math

A casual or recreational bettor whose action is driven more by team loyalty and recent results than by line value. Books welcome square money because it tends to be priced unfavorably.

Square Money Industry Slang

Action coming from recreational bettors, typically high volume but low average stake. Books welcome square money because it is usually priced unfavorably relative to the true line.

Stake Money, Odds & Vig

The dollar amount risked on a wager. In decimal odds notation, the return includes the stake (2.50 means a winning $10 stake returns $25). In American odds notation, profit is calculated separately from stake.

Steam (Steam Move) Industry Slang

A rapid, coordinated line movement caused by sharp money hitting multiple books at once. Books reprice quickly to avoid being picked off. Watching steam moves can signal where sharp money is landing.

SWC-Licensed Operator Tennessee-Specific

A sportsbook approved by the Sports Wagering Council to take wagers from Tennessee residents. The current ten licensed operators are DraftKings, FanDuel, BetMGM, Caesars, bet365, Fanatics, ESPN BET, Hard Rock Bet, Bally Bet, and VIP Play. Unlicensed offshore books are illegal to use in Tennessee.

Take Points Industry Slang

Betting on the underdog and getting the point spread. "Taking 7" means backing a team at +7. The opposite of lay points.

Teaser Bet Type Basics

A modified parlay that lets you adjust each leg's point spread or total in your favor by a set number of points (commonly 6 in NFL). All legs must still win. Teaser payouts are lower than standard parlay payouts because of the price you pay for moving the lines.

See also: /guides/parlays/

TELC (Tennessee Education Lottery Corporation) Tennessee-Specific

The predecessor regulator of Tennessee sports betting, responsible for licensing operators from launch on November 1, 2020 until the Sports Wagering Council took over on January 1, 2022.

Tennessee REDLINE Tennessee-Specific

HB 1 / SB 16, passed by the Tennessee General Assembly in April 2019 and signed into law by default in July 2019 when Governor Bill Lee allowed it to pass without his signature. Created the legal framework for online-only sports betting that launched November 1, 2020.

Three-Way Line Markets & Lines

A market with three outcomes: home win, draw, away win. Common in soccer and offered in hockey (settled in regulation only). Sometimes called 1X2 in European books and at bet365 Tennessee.

Total (Over/Under) Bet Type Basics

A bet on the combined score of both teams. Bet over if you expect the combined score to exceed the number, under if you expect it to fall below. Most totals price at -110 each way. Half-point totals (47.5) eliminate the push possibility.

See also: /guides/totals/

Tout (Tipster) Industry Slang

Someone who sells betting picks, often with inflated win-rate claims. Reputable tipsters publish full transparent records; many do not. Tennessee bettors should evaluate touts on long-run ROI rather than recent hot streaks.

Two-Factor Authentication (2FA) Sportsbook Operations

An additional login security step that requires a one-time code from SMS, email, or an authenticator app. Strongly recommended on every TN sportsbook account, especially those funded with PayPal or VIP Preferred.

Underdog Bet Type Basics

The team or outcome priced with positive moneyline odds, indicating less than 50% implied probability. Plus money payouts reflect the lower expected win rate.

See also: /calculators/implied-probability/

Unit Money, Odds & Vig

A standard bet size expressed as a percentage of bankroll, used to make pick-record discussion comparable across bettors with different bankroll sizes. 1u typically equals 1% of bankroll. Tracking units rather than dollars enforces discipline.

Value Bet Strategy & Math

A wager where the offered price implies a lower probability than the true probability of the outcome. Identifying value bets consistently is the foundation of long-term betting profitability.

Verification Sportsbook Operations

The KYC process completed at account opening or before first withdrawal. TN sportsbooks require name, DOB, address, and last four of SSN. Verification usually completes in minutes but can take longer if records do not match.

Voided Bet Sportsbook Operations

A bet that is canceled and the stake refunded. Common reasons include canceled games, postponements without rescheduling within the rule window, player scratches on player props, and obvious pricing errors.

Whale Industry Slang

A high-stakes recreational bettor whose handle is large enough that books actively court the action with concierge service, hosted events, and personalized promotions. Tennessee whales typically operate through DraftKings or BetMGM.

Withdrawal Sportsbook Operations

Transferring funds from your sportsbook balance to a bank account, e-wallet, or other linked payment method. PayPal withdrawals at TN books typically clear in under 24 hours; bank transfers take 24 to 72 hours.
