Five Nights at Freddy's launched in 2014 as an indie horror game by Scott Cawthon, built around watching animatronic characters through security cameras until one reaches the player. Its game over moment produced the FNAF Jumpscare Scream, a blast that became the series signature across sequels, videos and fan games. Clips spread through Let's Play reactions on YouTube, where exaggerated scares drew huge audiences. The sound survived outside the games because it is instantly identifiable, brief, and effective even without visuals, making it a standard shorthand for horror jump scares online.
