Among Us is a social deduction game developed by Innersloth and released in 2018, becoming widely popular in 2020 through streams and online play. Players complete tasks aboard a map while impostors secretly eliminate crewmates, and vents let impostors move unseen between rooms. That mechanic made venting a shorthand for suspicious behaviour in the community, spawning memes about catching someone mid-vent. The sound itself became a reusable editing cue beyond gameplay, used to mark any quick, sneaky disappearance in meme videos, streams and short clips shared online.
