Among Us is a social deduction game by Innersloth, first released in 2018 and widely popularised in 2020 when streamers and friends groups turned its crewmate-versus-imposter matches into a shared online joke. In each round, most players complete tasks while a small number of imposters secretly sabotage and eliminate crewmates, and the tension comes from not knowing who to trust. Clips tied to the imposter role spread through gameplay videos, memes and soundboards because that hidden-role moment is instantly recognisable even to people who have never played, and it still works as shorthand for suspicion and secret betrayal.
