A sexual act in which a male partner defacates on the floor, then tags his partner doggie style while holding their head inches over the shit on the floor. Usually the partner "ground-pounding" yells "You can't have it!!" several times as they keep their partner's face over the shit by their hair. Then eventually the partner then yells "Oh you can have it!!!!" and smashes their face into the shit. Thus giving them "The Ground-Pound".

Those sedatives put his dick in the ground.

Dude, that is nasty!
Yeah bro, and you're just getting the second-hand smoke. It's 10 times worse at ground zero.
