The art of upper-decking a toilet, getting a blowjob as they're also taking a dump in the bowl.

Hi-Brow Blumpkin 

The act of two people defecating on the same toilet while one receives fellatio. One person relieving themselves in the tank and the second facing them also passing excrement in the actual toilet. Thus referring to the hi brow part, being that the person on the tank is eye-brow level with the person on the bottom.

Man I just received the most amazing Hi-brow Blumpkin from a tranny in a Cahokia gas station.
