The sound comes from Five Nights at Freddy's, the indie horror game released by Scott Cawthon in 2014. When an animatronic reaches the player's office, the game cuts to a shaking close-up of its face while this harsh jumpscare scream blasts at full volume. Reaction videos from Let's Play creators turned that moment into one of the most imitated scares on YouTube, and the clip has circulated on soundboards ever since, sometimes misspelled as FRAF. It remains a shorthand for sudden, loud horror in memes and prank edits.
