Place this clip as the main segment after the surprising quote, not as a background bed. Follow it with a yeah reaction for agreement, then a funny laugh to close the bit before returning to the original footage and dialogue.

This clip is a 74-second song excerpt titled Q Q Vc Falou, listed by its uploader as an Eriva song, built around that repeated Portuguese phrase. It feels playful and a little incredulous, like a musical double-take when someone says something surprising and you want them to repeat it, which makes the long excerpt work as a running joke rather than a quick sting.
