toilet tank

A twist on the “tanking” sexual practice of inserting the testicles into an orifice (normally the pussy), toilet tanking is fucking someone in the ass and inserting the balls inside the ass.

I haven’t seen your mom since I toilet tanked her two weeks ago.

Somebody who intentionally shits in the cistern (toliet tank).

You don't want to invite Tom to the kegger, because he is a habitual toliet tank defecator!
