a stool of such girth that it feels like giving birth
i thought that ass-baby was gonna rip my ring!
When a gay man fucks his best girl-friend so hard up the ass that is creats a small hole through which an egg can travel from the ovary to the rectum. Then when he ejaculates into her ass she becomes pregnant and nine months later a baby explodes out of her ass. It's an Ass-Baby
"Lindsey, your butt has gotten really big"
"yeah, it's russles Ass-Baby, it's gonna explode out any day now!"
Your Ass-baby is covered in shit!
