When two people are having anal sex and the man takes out his penis and rubs it on the women's lips forming a mexican mustache/moustache. (The growth of hair between the nose and mouth.)

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.

Ok, this is the official way to give a dirty sanchez people, get it straight. First you must be doing a girl doggy-style, then you stick a finger in her asshole, and reach around to administer the poo-stache.

ALL OF YOU ARE WRONG!!! It's when a girl is on her period and a guy takes the tampon out with his teeth, then shakes it back and forth leaving two red stripes.
