Among Us was released by Innersloth in 2018 and exploded in popularity in 2020, when its social deduction matches became a staple of streams and group chats. Only impostors can use the vents scattered around each map, letting them move unseen between rooms, which quickly made venting slang for suspicious behaviour. Clips and sounds like this one spread through Discord servers and meme edits alongside related jokes such as Amongus Sus, keeping the vent cue alive as shorthand for someone sneaking away or getting caught.
