This sound is associated with Among Us, the multiplayer social deduction game that became a major online meme in 2020. Creators began using the impostor reveal audio and its tense mood far beyond gameplay, especially on short-form videos and reaction edits. It stayed popular because the word and sound instantly communicate that someone is acting suspicious. It is often used alongside other quick meme reactions such as bruh or a buzzer when a joke needs an obvious guilty reveal.
