dirty nanchez 

A belligerent, egocentric, cunt with an elitist complex. A derivative of a succubus, the dirty nanchez or big fizz is spawned from Satan himself. She has no friends but remains petulant to the few that have the reccesive trait to stand her company. The only known way to escape this foul creature is to dump a pound of her flesh in battery acid and set it aflame.

The dirty nanchez has sucked another soul out of another innocent boy.

When two people are engaged in sex, one person, usually the male, inserts their finger in the anal cavity of their partner, and proceeds to wipe particles of feces on the upper lip of their mate.

My girlfriend and I were having sex last night, and right after I had an orgasm I gave her a dirty sanchez.

When your getting some brown lovin' and you smear some shit on your lovers lip making her look like shes got a brown mustache.
