Definition: A tie against the spread. On straight bets the result is "no action." All monies are returned as if the bet had never been made. On parlay cards typically the number of teams in the parlay is lowered by one to account for the push.

 

Example: Duke was favored by 10 and won by 10, pushing the game. Bob's six-team parlay included Duke, so it became a 5-teamer.
