Place this clip right after the awkward reveal in your edit, then follow it with a bruh for the deadpan payoff or cut straight to an oh my god meme for a bigger shocked reaction.

This is a short voice clip of a man exclaiming the Spanish phrase "me da vergüenza," meaning I'm embarrassed. The 1.5-second line is delivered with cringing, second-hand embarrassment, which makes it feel awkward and funny at the same time, like a public blush caught on microphone.
