Among Us launched in 2018 from indie studio Innersloth, but it exploded in 2020 when streamers turned its social deduction gameplay into appointment viewing. Crewmates hunting the impostor shortened 'suspicious' to 'sus' during emergency meetings, and the word escaped the game to become one of the decade's biggest memes, spawning remixes, animations and the amogus parody wave. It stuck around because accusing someone of being sus works anywhere: it pairs naturally with the enemy spotted alert when a culprit is caught, or with the fbi open up gag for a mock raid on the guilty party.
