The time's up buzzer comes from decades of television game shows and timed quiz formats, where a loud electronic buzz has long been used to signal that a contestant has run out of time or answered incorrectly. That association carried over to arcade games, school timers and sports clocks, making the sound instantly readable even without visuals. Online, creators adopted it as a meme shorthand for failure and finality, which is why queries like buzzer times up and time's up meme lead people to this short clip for edits, streams and soundboards.
