Put it immediately after the daft line in a reaction edit, then follow it with awkward crickets to let the insult hang, or a chipmunk laugh to close the edit on a lighter beat.

This is a short two-second voice clip built around the Spanish word 'imbécil', spoken in Melcochita's comic delivery. It lands as a blunt, playful insult, funny because it is direct and over the top rather than cruel, and it works best as a quick put-down for a daft comment, a bad take or a clumsy mistake.
