Among Us, the social deduction game from InnerSloth, turned the word sus into shorthand for suspicious when it exploded in popularity in 2020, and red quickly became the community's default suspect in memes and lobby jokes. Short voice clips accusing red spread through soundboards, TikTok edits and gameplay videos because the joke needed no setup for anyone who had played. It remains in use as a quick, recognisable accusation for any guilty-looking moment, inside or outside the game.
