Among Us is a social deduction game developed by InnerSloth, first released in 2018 and widely popularised by streamers in 2020, when clips of crewmates and impostors became a staple of short-form video. Its spaceship maps use sliding doors to separate rooms, and the short hiss and click became instantly recognisable to players. Creators later lifted the effect for memes and edits, often pairing it with the Among Us role reveal sound, because both cues instantly tell viewers that something hidden is about to be exposed.
