The sound comes from Five Nights at Freddy's, the 2014 indie horror game by Scott Cawthon, where animatronic characters attack the player with a loud scream and a sudden close up. As gameplay clips spread on YouTube and streaming platforms, that attack moment was isolated and reused far beyond the game. It became a staple scream meme for edits, compilations and prank posts, because viewers instantly recognise the shriek even without seeing Freddy or the other animatronics on screen at all.
