The scream comes from Five Nights at Freddy's, the indie horror game released in 2014 by Scott Cawthon. In the game it plays during a jumpscare when an animatronic reaches the player, ending the night. Let's Play videos on YouTube helped make the sound instantly recognisable beyond the game itself, as creators replayed the moment for reactions. It has since become shorthand for a sudden scare online, reused in edits, memes and soundboards whenever a reveal needs that familiar horror sting.
