This sound comes from Among Us, the multiplayer social deduction game developed by InnerSloth. The emergency meeting alert became widely recognizable as the game exploded in popularity during 2020 through streams, memes, and short-form edits. Online, people use it as a shorthand for stopping the action and demanding answers, especially when someone acts suspicious. It remains popular because even a very short snippet instantly signals accusation, panic, and comedy to viewers who know the game. Related Among Us edits often also use the Imposter Kill cue.
