Place this clip at the reveal point, after Sudden Suspense builds the setup, then follow it immediately with Oh My God Wow as the next reaction beat in the edit.
Über diesen Sound
This is a short, sharp scream lasting just over a second, delivered in a high, startled voice that rises fast and cuts off abruptly. It feels playful rather than frightening, like a cartoon gasp stretched into a yelp, and it works best as an instant burst of mock panic. The suddenness makes it funny, turning a small surprise into something dramatic without needing any words at all.
