Place it at the peak of a FNAF edit, after Dun Dun Dun sets up the moment and before Fortnite Death Sound marks the defeat. Keep the build-up quiet so the hit lands on a black frame, then cut straight to the reaction shot.
About this sound
This is the short two-second jumpscare sound of Foxy from Five Nights at Freddy's 1, a sudden burst of a distorted scream layered over a harsh metallic crash. It feels abrupt, startling and tense, like being caught off guard in the dark. The clip comes from the original game's jumpscare when Foxy reaches the office.
