"Sus" became mainstream slang through the social deduction game Among Us, which surged in popularity in 2020. "Amogus" grew as a deliberately misspelled, absurd meme variation of the game name across short videos, image edits and shitpost culture. The sound spread because it compresses the whole joke into two instantly recognizable words that viewers already understand. It remains popular in gaming memes and reaction edits where creators want a quick, low-effort cue for suspicion without needing a longer setup.
