Among Us, the social deduction game by Innersloth released in 2018, became a streaming phenomenon in 2020 as creators on Twitch and YouTube built entire channels around its betrayal gameplay. Short interface sounds from the game, including this clipped beep, were ripped and passed around as standalone meme clips, used to flag 'sus' behaviour in edits far beyond the game itself. Even after the hype cooled, the beep survived as shorthand for calling someone out, instantly readable to anyone who watched the era unfold.
