[TOMT] Song from a movie (Maybe TV Movie)

I only remember it being a very cringe worthy scene where a father and son appear to be on a college campus. The father says to the son, "You're afraid of girls!" The son responds and says, "Are not!" And the father says, "Are too!" And it goes on for a brief moment back and forth. Then the father busts out a boom box and starts singing a song.

The father throws in a couple nerdish laughs while he sings.

I've seen it on Reddit before, but I can't find it now.
