Among Us, developed by InnerSloth and released in 2018, became a hit in 2020 as streamers and friends played its social deduction matches online. In the game, impostors can travel through the vent system to move unseen between rooms, while crewmates cannot use vents at all, which makes the vent noise an instant tell. Clips of the sound spread through gameplay videos, memes, and short-form edits, where creators reused it to imply sneaking, hiding, or a surprise reveal even without any game footage. It remains popular because that association is understood by anyone who has played or watched the game.
