When a guy has anal sex with a girl then she gives him head and a shit mustache is left on her upper lip.

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 man's index finger was smelly after administering a dirty sanchez.

It does not matter how you do it. It's a Fecal Mustache.
Jane likes to give head, but Dick likes to give a Dirty Sanchez.

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 disgusting thing when the guy puts a finger in the females ass and spreads the crap on the upper lip.

my ex-boyfriend gave me a dirty sanchez at a party and said he cleaned it off but he didn't so when we came out of the room every one laughed at me! : (

An act characterized by the fingering of the ass and the giving of a "thin shit moustache." Not to be confused with the dirty rodruigez.
I was bangin' her ass and then I decided it would be a great idea to give her a dirty sanchez.
