Among Us is a 2018 social deduction game in which crewmates try to identify a hidden impostor, and the slang word sus, short for suspicious, became its most recognisable shorthand. Amogus grew from that same joke as a deliberately misspelled, distorted version of the game's name, spreading through TikTok, YouTube Shorts, Discord and gaming edits during the game's surge in popularity. The sussy variant keeps the joke compact and instantly readable, which is why creators still use it to flag a suspicious moment without needing any explanation.
