Top Definition
The sexual act of inserting a woman's breast into someone's anus. Because of the difficulty of the maneuver, only those with extremely loose anuses and large floppy tits have been known to successfully complete a poopboob.
It took 20 minutes of stuffing, but I finally pushed most of my boob inside. What a poopboob that was!
