The scream comes from Five Nights at Freddy's, the 2014 indie horror game by Scott Cawthon where animatronics jumpscare the night guard. The harsh audio cue became famous through YouTube Let's Plays, with creators like Markiplier amplifying the reaction. As FNAF grew into a franchise of sequels, books and a 2023 film, the sound detached from gameplay and became shorthand for any sudden scare online. It endures because the FNAF jumpscare scream is instantly recognizable, brutally loud, and perfect for short-form prank edits.
