The sound comes from Five Nights with Eazil's 3, a fan-made entry in the Five Nights at Freddy's fangame tradition where the jumpscare sting is the climax of every run. Short, loud attack sounds like this are the genre's calling card, and fangame versions circulate on soundboard sites because editors want fresh scares instead of the classic FNAF jumpscare scream. This particular scream has found a second life in prank and reaction edits, where its raw, distorted edge startles viewers even when they expect a jumpscare.
