Among Us is a social deduction game developed by InnerSloth and released in 2018, in which players complete tasks while trying to identify hidden impostors. The game became a global hit in 2020, and players shortened suspicious to sus, turning every accusation into a running joke. Clips, edits and remixes spread the slang far beyond the game itself, through streaming, short video platforms and meme pages. That shared language is why a brief sus reference still works instantly, even for viewers who have never played a round.
