Popular Sports Betting Terms and Phrases

A

Action

A term for how many bets placed and/or how much money is wagered on an event.

Against The Spread (ATS)

Bad Beat

A bet that looked like it was going to win before losing at the last second, usually due to bad luck or an unlikely play.

Betting Unit

Also simply referred to as a “unit,” this is the standard amount of money that a sports bettor will wager. The amount of the “unit” can differ from person to person. For one person, a unit can be $500. For another person, a unit can be $5.

Bettor

Cover

Short for “covering the spread”. When a team or individual beats the point spread, either by winning by more points than the given spread (as a favorite) or by not losing by more than the given spread (as an underdog).

For example: If the Buffalo Bills are favored by 10.5 points (-10.5) over the Miami Dolphins and win 31-20, they will have covered the spread. But if they beat the Dolphins 31-24, that means the Dolphins will have covered the spread as a 10.5-point underdog (+10.5).

D

For example, the favorite in a horse race could have 2/1 odds to win, while the second favorite could have 5/2 odds to win.

Futures/Futures Bet

A type of long-term bet that will be graded at a later date (near or far). The most common types of futures bets are wagers on a sports team to win their season-long championship (Super Bowl futures, World Series futures, NBA championship futures, and Stanley Cup futures, to name a few examples).

This term can also be used when referring to a wager on a season-long award, a team’s season-long win total, or an event that’s set to take place sometime in the future like an entertainment awards ceremony, election, a tennis tournament, a boxing or UFC match, and much more.

A spread or total that does not have a hook has a chance of landing directly on the given point spread or total number, which would result in the bet being refunded.

L

Laying the Points

A slang term for betting on a favorite on the point spread.

You are “giving” the underdog team a certain number of points in order to get longer odds than a moneyline bet would offer. This is the opposite of “taking the points.”

For example: If the Buffalo Bills are favored by 10.5 points over the Miami Dolphins in an NFL matchup, and you bet on the Bills to cover the -10.5, then you are laying the points.

Limit (Betting Limit or Wager Limit)

The maximum that a sportsbook will allow you to wager on a given event or game.

Lines

Another term for sports betting odds.

Line Movement

Lock

A slang term for a bet that is perceived by a bettor as a guarantee.

Long Odds/Long Shot

When something is less likely to happen, the odds are considered “long”.

Betting on an underdog would mean that you’re betting on “longer odds” than you would be if you were wagering on the favorite.

For example, if Vanderbilt has +1800 odds to beat Georgia in college football, they have very long odds to win.

M

Middling

Middling is a form of hedging bets and is often used with point spread betting in football and basketball. If someone has placed a bet on one side of the point spread, then take action on the other side of the point spread after significant line movement has occurred in an attempt to win both bets if the result lands in between the two spreads, this is middling.

Moneyline

A moneyline bet is a straightforward wager on a person or team to win a game/event without involving a point spread.

When betting on a favorite on the moneyline the payout will usually be much smaller than it would be if you were betting on the point spread.

When betting on an underdog on the moneyline, the payout will usually be much larger than it would be if you were betting on the point spread.

N

Nickel/Nickel Bet

A slang term for a $500 bet. A “big nickel” bet is a $5,000 bet.

Another term for a “total” bet which is most commonly a bet on how many total points will be scored in a game.

It can also refer to a bet on the amount of any other measurable statistic in an event that can be wagered on. For example, many prop bets are over/under bets.

P

Parlay

A bet that has multiple different “legs” included. Each game or “leg” included in the parlay must hit for the parlay to be considered a winner.

For parlays–which are also known as combination “combo” bets or accumulators–much higher payout is offered than what would be possible if each leg was bet individually.

Pick’em

  • Buffalo Bills -10.5 (-110)

The side of a bet that is receiving a higher percentage of wagers. Usually referred to as the “public side” of a bet.

When a bet neither wins nor loses due to the game ending in a draw or the result of the event lands directly on the given point spread or total. In these instances, sports betting sites will typically refund the betting stake.

Example: If the total for the Philadelphia Eagles vs Dallas Cowboys game is 45, and the Cowboys defeat the Eagles 24-21, then there is a push for over/under bets.
