Among Us is a social deduction game by InnerSloth, first released in 2018 and widely popularised in 2020 through streamers and short-form video. In each round, crewmates gather for an emergency meeting to discuss suspicious behaviour and vote out a possible impostor, and that discussion phase gave rise to the slang word sus. Clips from these moments spread across TikTok, YouTube and Twitch, where the accusation format became a shorthand joke for distrust, and it remains a popular sound for gaming edits and reaction videos.
