Among Us was released by Innersloth in 2018 and exploded in popularity in 2020, when streamers and TikTok creators turned its crewmates, impostors and emergency meetings into a shared meme language. Short interface sounds from the game were clipped and reused outside gameplay, with beeps and alarms becoming shorthand for calling out someone as sus. This diiit diiit version circulated as a TikTok trend sound, detached from any specific round of the game. It remains popular because the reference is instantly recognisable and the joke needs no setup or explanation.
