Put it right after the reveal or double-take, as the beat that marks the moment, then let Awkward Crickets carry the silence that follows. For a bigger escalation, follow it with Shocking Sound Effect instead, so the flinch opens the reaction and the second cue raises it.

The clip is a sub-second effect centred on one abrupt twitch, over almost before it begins. It hits as a quick jolt that cuts straight into a scene, with nothing spoken and no lead-in to soften it. Listeners get an immediate flash of surprise that feels overdone on purpose, so a plain look, pause or reveal suddenly reads as a comic flinch.
