Place it immediately after a horror sting in the edit, then follow it with a confused reaction line. Pair it after the FNAF Jumpscare Scream to flip fear into comedy, or before No God Please No for a regret payoff.
About this sound
This clip is the drawn-out Wazzup shout from the phone scene, a stretched nasal yell that stretches a simple hello across almost five seconds. It feels goofy, loud and slightly unhinged, turning a normal greeting into an absurd interruption. It comes from Scary Movie, the 2000 horror parody that spoofed Scream.
