Ground Zero

The close proximity around a person who has just expelled exceedingly unpleasant gases from their anal passage. Also the site of splashdown while offloading previous meals into the toilet.
"I'd give it five minutes mate, it's Ground Zero in there."

"Oh god, sorry mate, it's Ground Zero in my pants" (wafts in colleagues' face)

The Ground-Pound

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".
The Ground-Pound is just plain nasty!
