Five Nights at Freddy's is a 2014 indie horror game in which the player watches security cameras and survives nights against hostile animatronic characters, and a jumpscare is the sudden attack that ends a run when one reaches the office. Clips of those screams spread through YouTube playthroughs, reaction videos and horror compilations, where the loud, abrupt sound became shorthand for failure and shock. It remains popular because fans recognise it instantly, even without seeing the game, and creators reuse it to add horror-game tension to pranks, edits and short-form videos.
