Parrot Banter 

When two people, typically good friends or relatives, get into an argument not for the sake of getting their point across, but to hear themselves talk.

The arguments are typically about topics neither knows much about, or they choose sides which they don't truly support, all for the sake of comedy.

Person 1: What are those two talking about?

Person 2: I don't know, parrot banter I guess.
