When you and a girl have very drunken sexual relations with each other. Unfortunately, this girl is on her period. Godfathering occurs when you wake up with blood all over your crotch and body, and wake up screaming.
Guy: Me and this girl hooked up last night, but she didn't tell me she was on her period.... Not a pleasant sight in the morning.
Friend: DUDE, you just got Godfather'd!!
