Five Nights at Freddy's is a 2014 indie horror game in which the player survives night shifts at a pizza restaurant while animatronic characters move toward the office, and being caught triggers a sudden jumpscare with a loud scream and a close-up face. Clips of those moments spread widely on YouTube, Twitch and TikTok as streamers reacted to them, turning the scream into a recognisable horror shorthand. It remains popular because the sound instantly signals danger and surprise, even for viewers who have never played the game.
