Place it as the immediate reaction beat after the visual reveal, before any commentary resumes. For a bigger build, lead in with sudden suspense, then follow this clip with a nelson ha ha when the embarrassment needs a mocking finish from the group.

This five-second clip is a single throaty 'aahhkk' vocal, somewhere between a gasp, a shout and a startled yelp, finished with a pronounced trailing echo. It feels absurd and overblown in a funny way, turning shock, disgust or panicked confusion into something bigger and sillier than the moment deserves.
