Place it after the reveal beat in your edit, not during the build-up. Lead into it with the sudden suspense sound to set the moment, then follow it with the oh my god wow button when you want a second reaction from another person on screen.

Cibil is a 4-second voice clip built around a loud, drawn-out shout of 'YHAAA' that carries the whole recording. There is no music or background effect behind it, just that single exaggerated vocal burst. It feels funny and startled at the same time, the kind of outsized reaction that makes a small moment sound suddenly dramatic and silly.
