This sound is commonly identified by players as the breathing cue from Five Nights at Freddy's 4, the 2015 horror game where listening carefully is a core mechanic. Online, the clip spread through gameplay videos, compilations, and fan edits because it represents the exact moment a player has to stop and react. It is still used in short videos and memes because the sound alone communicates suspense to anyone familiar with FNAF, even without showing the game itself.
