This sound comes from Five Nights at Freddy's 4, the 2015 survival horror game by Scott Cawthon. The game's nightmare animatronic attacks helped popularize this kind of piercing horror sting in YouTube compilations, reaction videos and stream highlight edits. It remains widely used because it instantly signals a jumpscare, even out of context, and its short, explosive mix works well in memes. Online, it often gets reused alongside other scream meme audio for exaggerated surprise or panic.
