Among Us is a social deduction game from Innersloth that first launched in 2018 and exploded in popularity in 2020, when streamers and short-form creators turned its emergency meetings, tasks and impostor accusations into a wave of memes. The word sus, short for suspicious, became shorthand for accusing a crewmate, and compilations of its sounds spread across TikTok, YouTube and Discord as quick reaction audio. It remains popular because the format is instantly understood, even without playing the game, and a few seconds of its sounds can signal betrayal, doubt or a joke vote.
