Among Us, released by InnerSloth in 2018, became a streaming phenomenon in 2020, when its hidden impostor role turned ordinary group games into viral clips about lying and betrayal. The word sus, short for suspicious, spread from the game into everyday meme language, and later merged with baka, the Japanese word for fool, to form the TikTok phrase sussy baka. That crossover kept the impostor joke alive long after the game's peak, because it works as shorthand for anyone acting secretly guilty.
