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. The word sus, short for suspicious, became the game's defining slang as players accused each other of being the hidden impostor during emergency meetings. That shorthand spread far beyond the game through TikTok edits, Twitch clips and YouTube memes, where a single accusation could turn an ordinary moment into a joke. It remains popular because the reference is instantly understood even by people who have never played.
