Among Us, the social deduction game by InnerSloth released in 2018, exploded in popularity in 2020 as streamers popularised its crewmate and impostor gameplay. Players shortened suspicious to sus, and the word quickly escaped the game into memes, edits and reaction videos. The red crewmate became a visual shorthand for the joke, and short clips like this one kept it alive long after the game's peak, because the accusation works in almost any situation where someone looks guilty.
