When you go into a bathroom at a resturant or any public place and you have to take a shit and you climb up on the top of the stall and go from up there and when it lands it resembles a bomb, hence the name.
Herget went in to Zaxby's last night and powerbombed their bathroom, what a sick fuck.

While engaging in the standard pile-driver sex position, lift your partner, and powerbomb that ho' onto a table. If the table breaks, it is referred to as the markly powerbomb.
Yesterday, when me and mah' ho' were doing it pile-driver style, I decided we needed to take it to the kitchen table, and I powerbombed that ho'!!!
