What "buzzer beater" means in basketball

"Buzzer beater" is a term used in basketball to describe a shot that is made at the very last second before the game clock runs out. This type of shot usually occurs during a close game, where the final score can be greatly affected by the success or failure of this last-second attempt. A buzzer beater can be a game-winning shot, or sometimes it may only impact the final score by only a few points.
