Among Us, developed by Innersloth and released in 2018, became a global hit in 2020 as streamers and friends played its social deduction matches online. In that setting, players shortened suspicious to sus when voting out a possible impostor, and the word quickly escaped the game into everyday meme language. Short clips tied to that joke spread across TikTok, YouTube and Discord, where creators reused them to flag shady behaviour in unrelated videos. The term remains popular because it is instantly understood, even by people who have never played the game.
