Place it at the peak of a horror sequence after a slow buildup scene, then follow it with the FNAF Jumpscare Scream for a second hit, or open with the Danger Alarm Meme to warn viewers before the scare lands.
About this sound
This three-second clip is a loud monster yell built for a jumpscare, with a harsh, distorted roar that hits all at once. It feels sudden and frightening, the kind of shock that makes a listener flinch before they can react. It comes from the FNAF horror games, where that yell signals a monster attack.
