The jumpscare sound comes from Five Nights at Freddy's, the indie horror game released in 2014 in which players survive nights against hostile animatronics. When an animatronic reaches the player, the game cuts to a sudden close-up accompanied by a loud screech, a moment that became a signature of the series. Clips of that scare spread through Let's Play videos and horror compilations, and editors still reuse the sound today because it instantly signals danger, panic, and a failed run.
