term used to describe the last effort used to talk a girl, usually a girlfriend, out of having your baby because she refuses to have an abortion. If successful, the guy usually celebrates by breaking up with the girl.
Suzi: Tom, I am pregnant with your kid and I won't have an abortion.

(time for a hail mary by Tom)

Tom: Suzi, I love you very much and would like nothing better than to have children with you. But, if we have a child now, that will ruin our chances of having a huge wedding, buying a home and raising many wonderful children together. If you have an abortion now, I promise we will have many children later.
