Contrarian Betting – Also known as betting against the public, contrarian betting finds value by betting on games with lopsided betting percentages.

Cover – In sports such as football and basketball, a bettor wins their bet if they cover the point-spread. For example, if you bet a 7-point favorite and they win by 9, you have covered the spread.

Dime – A bet of $1000.

Dog – Short for underdog, this is the team which bookmakers assume will lose the game.

Draw – Also known as a push. If a game falls exactly on the spread, there is no winner and bettors will receive their money back.

Edge – A bettors advantage against the house. This will typically refer to an instance where you have a positive expected value.

Even Money – A bet where you are not paying any vigorish (i.e. +100).

Favorite – The team bookmakers expect will win their game.

Field – Often time in proposition (prop) bets, bettors are allowed to bet the field. This refers to an accumulation of all the teams or players that are not listed specifically.

Future – This refers to bets that come down in advance of an event. For example, one can bet a Super Bowl future prior to the beginning of the season by selecting who they believe will win the championship. A bettor would receive payment at the end of the season if their selection did claim the title.

Hedging – Placing bets on the opposite side after you have already placed a wager on one side. This can be used to either cut your losses, or guarantee a profit.

Hook – In spread based sports, the hook is an extra half-point that bettors can get. Often times in football, bettors will buy the hook around key numbers like 3 to get a line of 3.5.

Grand Salami – This typically refers to the over/under total for how many goals/runs will be scored across all games in a specific league.

Juice – This is the tax that sportsbooks create for placing a wager. Typically, books offer a dimeline (-110) which means that you need to win 52.38% of your bets to break even. Some books will offer reduced juice with lines between -104 and -107.

Key Numbers – This represents the most common margins of defeat, and is used frequently in football where many games end with one team winning by a multiple of 3 or 7.

Limit – The most money a sportsbook will take on a single event.

Lines – Another term for the odds.

Middle – This occurs when you bet on both sides of a game and have an opportunity to win both bets. For example if you bet on Team A +10.5 and Team B -7.5, you would win both bets if Team B wins by 8-10 points.

Moneyline – In sports like baseball, soccer and hockey, there are so few goals scored that it would not make sense to offer a spread. Instead, these sports offer a moneyline in which you bet on whether or not a specific team is going to win straight up.

Nickel – A bet of $500.

Off the Board – A game or event that is sportsbooks will not allow you to bet on. Often times a game is taken off the board if their is uncertainly surrounding a player’s injury status or the weather.

Over/Under – Also known as the total, this refers to the total amounts of points/goals/runs that will be scored in the game. If both teams combine to score more than the total, the over wins. If they combine to score less, the under wins.

Parlay – When a bettor makes multiple bets (at least two) and ties them together, you need multiple events to all win for higher payouts. This is a risky proposition, but potentially very lucrative.

Pick ‘Em – An instance in which neither team is favored. In spread based sports like basketball or football, this would equate to a line of 0.

Prop Bet – A bet on something other than the outcome of a game. Common prop bets include an over/under on points scored, passing yards, or strikeouts by an individual.

Public Betting Percentage - Also referred to as public betting trends, we offer real betting percentages from seven contributing sportsbooks. These numbers represent real bets placed at real sportsbooks. These percentages are integral for our betting against the public philosophy.

Push – When a contest ends without a winner. In a moneyline sport this would happen if the game ended in a tie. In a spread sport, this would happen if the favorite wins by the exact spread.

Reverse-Line Movement – Betting line movement that contradicts the public betting percentages. For example: if Team A is receiving 80% of the public bets as a 7 point favorite yet the line drops to -6.5, this is an example of reverse line movement. This would indicate that sharp money is taking Team B.

Return on Investment (ROI) – A performance measure used to evaluate the efficiency of an investment.

Run Line – In moneyline sports like baseball or hockey, you can take the equivalent of a spread — the run/puck line. This alternative allows you to add runs for the underdog, or subtract them from the favorite. This means that a favorite would have to win by at least 2 runs for you to win your bet, while an underdog could either lose by 1 run or win straight up to win the bet. The benefit of this is that you can more lucrative lines on favorites, but because baseball and hockey are such low-scoring games, this can be a risky proposition.

Runner – An individual who places a bet on behalf of another person.

Steam Move - A sudden drastic and uniform line movement across the entire sports betting marketplace.

Teaser – A special bet in which you are able to adjust the point spread or total for a game. The more you change the spread, the lower the payout becomes.

Tout – An individual who sells their picks or their sports betting expertise to others.

Units – At SportsInsights, we constantly count our winnings according to units won. We recommend betting one unit per game, which refers to  a standard monetary measurement — typically between 2-4% of your bankroll. For example if your bankroll was $1000, one unit would be between $20 and $40. Then if you noticed a system that had won 15 units over the season, you could easily calculate your earnings by taking the units earned and multiply them by your standard betting unit (in this case, $20 x 15 units = $300).

Wager – Any type of bet.
