Very rare, but it occurs when you are nailing a chick in the ass so hard that your dick tears through the lining of her ass, bursts into her uterus, and you mistakingly impregnate her.
Shit, I was trying to be safe last week with nina by going anal, but I accidental rectegnated her. Rectegnation blows, I'm so screwed.
