The sound comes from Five Nights at Jliarry's 3, a fan-made horror game inspired by the Five Nights at Freddy's series, where phantom characters suddenly appear on screen to startle the player. Clips of that moment were shared on soundboards and in horror gameplay videos, where the short, harsh noise became easy to reuse outside the game itself. Like the classic FNAF jumpscare scream, it is now used by creators who want an instant scare without explaining the game, and it stays popular because horror fans recognise the style and new viewers still jump at the noise.
