Place this clip at the reveal point of the edit, after the setup shot and before the response beat. Lead in with the oh my god wow reaction for surprise, then use this clip, then follow with the eww brother eww line to extend the disgust sequence.

The clip is a short voice reaction, about four seconds long, built around a single spoken French word for something disgusting, delivered as an outburst. It gives a listener a blunt feeling of revulsion mixed with comedy, like a verbal recoil that makes a nasty moment feel exaggerated and funny rather than genuinely unpleasant or serious.
