The chant comes from the Amogus meme, a 2021 offshoot of Among Us, the 2018 social deduction game by Innersloth that became a global hit in 2020. Players began deliberately misspelling the game's name as 'amogus,' and shitpost editors paired the word with a distorted deep voice chant over a stretched, low-resolution image of the red crewmate. The format spread through TikTok and YouTube meme compilations, where the chant became shorthand for anything suspicious. It endures because the game is still played and the word is instantly recognisable to meme audiences.
