The sound comes from TRTF 5, short for The Return to Freddy's 5, part of a long-running fan-made series inspired by Five Nights at Freddy's. Like the official games, it relies on animatronic characters lunging at the player with a loud scream to end a night. Clips of that moment were ripped and shared on soundboards alongside the classic FNAF jumpscare scream, and editors began reusing the audio outside gameplay. Its brevity and extreme volume kept it popular for horror edits, reaction videos and scare pranks.
