This jumpscare comes from FNaG ACP2, a fan-made game inspired by Five Nights at Freddy's, where surviving animatronic attacks is the core of the gameplay. In the game, a jumpscare marks the moment a player is caught, so the sound quickly became a shorthand for sudden failure and panic in fan edits and gameplay clips. As FNaF fan games spread through YouTube and short-form video, the clip travelled with them, and creators still reuse it because it instantly signals danger, even to viewers who have never played the game.
