This sound is associated with Five Nights at Freddy's 2, the 2014 survival horror game in Scott Cawthon's FNAF series. Fans recognize it as part of the game's tense audio atmosphere, especially in clips focused on hallways, threats and incoming animatronics. It spread through gameplay uploads, reaction videos and short horror edits, where creators use it as a quick cue that something unsettling is nearby. It still gets reused because even a few seconds of it immediately signals FNAF-style suspense to gaming audiences.
