poop-tank

The two-cheecked, vertically split hemi-sphere that you would be lost inside if you travelled about 6 inches aft of the vagina along the grundle.

After like half an hour of wearing the hinges off this girl's front door, she finally got on all fours, and looked back at me with a look that said, "put it in my poop-tank or get out."

Tankslap

The fine art of slapping one's "semi" off one's stomach to impress one's annoyed girlfriend. Also works with gay boys, apparently

I tankslapped and she was not impressed. Pah.

Tankslap

To hit someone or something with your penis.

"What sound does a tankslap make? DONG!"

"Man, if she does that to me one more time, I'm gonna tankslap that whore."

hump tank

N.
Essentially a bachelor pad, but more specifically the master bedroom. Obviously when you enter the hump tank the obvious follows, the trick is to get them in there.
