Buzzer beater

In timed sports, a buzzer beater is a successful shot made as the clock expires at the end of a period or at the end of the game, leaving zero seconds remaining. A buzzer sounds whenever a game clock expires, hence the name “buzzer beater.” In basketball, the concept normally applies to baskets made at the end of a quarter, the second half, or overtime. A buzzer beater only counts if it leaves the player’s fingers before the shot clock runs out. If the ball remains in the player’s hands, then the shot violates the Trent Tucker Rule and does not count. The term is most commonly applied to shots that win or tie the game as the game clock expires.
