Freddy Fazbear is the mascot animatronic of Five Nights at Freddy's, and this scream comes from Five Nights at Freddy's AR: Special Delivery, the 2019 mobile game by Illumix that brought the animatronics into the player's real surroundings through the phone camera. In the game, failing to fend off Freddy triggers this full-screen FNAF jumpscare and its harsh audio sting. Clips of AR jumpscares spread quickly on YouTube and TikTok, and the isolated sound became a staple on meme soundboards for pranks, where its short length makes it easy to drop.
