Place this clip as the punchline after the setup line in your edit, not underneath dialogue. Follow it with the emotional damage hit for a second beat, or swap in a bruh reaction for a drier, quicker response.

A six-second voice clip of a guy delivering the line country boy I love you with an exaggerated drawl and a long trailing ehhh at the end. It feels playfully awkward and over-earnest, like a confession said too loudly at exactly the wrong moment, which makes the whole thing land as silly rather than sweet.
