Among Us is a social deduction game in which crewmates try to identify the imposter among them, and its name became a running joke online as the game surged in popularity in 2020. Players and creators began stretching the title into a long, suspicious drawl, often with a deep voice-changer effect, to signal that someone was acting sus. The sound spread through short videos, streams and meme edits, where it works as instant shorthand for suspicion. It remains popular because the joke needs no setup for anyone familiar with the game.
