TV Trope: Volleying Insults

Jeff: Listen backseat birther. Shirley’s on her third kid, she doesn’t need a thirty-year-old slacker with two one-eyed cats governing her body.

Jeff: I regret nothing.
Britta: I feel sorry for the airhead you’re going to knock up at the age of seventy. You’re going to be sitting in the waiting room playing Solitaire on your Blackberry while a life is created ten feet from you.
Jeff: Oh, and you’re going to squat in a babbling brook and a beautiful star-child is going to slide out on a ray of sunshine while your cats each half watch because you’re so natural.
