A premature baby. Coined by Adam Carolla on his podcast(1/18/13).
Pat:Did you hear, Megan Shanahan had another miscarriage?
Connor:Aye, can't say I'm surprised.
Connor:She snaps Irish footballs every other month.
Pat:Yeah, ya really gotta stop knocking her up.
Connor:Aye, probably should stop coming home bleeding drunk and beating her within an inch of her life as well.
