You guys are wrong, its when a man and a woman engage in anal sex, then the man takes his penis and rubs it on the girls upper lip leaving a moustache.
After having anal sex, the man gave the woman a dirty sanchez.

NO, a Dirty Sanchez is performed when a male fingers a female's ass and wipes the reminants on the female's upper lip. What you referred to below, when a male inserts his penis in a female's ass then transfers the fecal matter from his penis to the female's upper lip is the Dirty Rodruigez, the first cousin of the Dirty Sanchez. Don't feel bad though, they are commonly confused.

The term 'dirty sanchez' originated in the porn industry, particularly films involving ass-to-mouth (atm) action. It describes the (originally unintentional, i.e. blooper) act of leaving a shit moustache on a partner's face by taking your cock out of her ass and putting it in her mouth without wiping it off first. The result is that as the dick is thrust between the lips, shit is scraped off and comes to rest on her upper lip in a moustache configuration.

Anyone who thinks it involves the deliberate wiping of shit with fingers on a partner's face is a know-nothing fucktard.
Please disregard the numerous fucktard definitions of 'dirty sanchez' that were previously recorded.

A Dirty Sanchez is when the man cums in the asshole and then takes the cum out with his finger and makes a mustache on the females face.
