What is #1 Son Refund?
The act of male sexual reciprocation of maternally projected loathing or the sexual manifestation of self-loathing superimposed onto the mother/son relationship by means of some sort of Oedipal paranoia.
ie: When a motherfucker fucks his mother because fucking his mother is the closest a motherfucker can come to crawling inside of her and physically reversing his birth.
Justin - How come you don't laugh at my jokes, mom?
Mary - Because your a mean and vulgar boy!
Justin - Jeez! What do you want from me? A #1 Son Refund?
Mary - I don't know what that is, but I've read The Bible five times and I'm not going to listen to you tell me about it!
