latin: Clunis Concubitis Barba
After a man and woman engage in anal sex, the maile removes his still-erect member from his partner's rectum and rubs it along her upper lip, thus creating a sort of fecal mustachio supposedly reminiscent of a scraggly Mexican mustache, or bigote.
Women love being Dirty Sanchezed because of the power reversal and gender switch that comes from having a typically masculine mustache painted across their face with a penis

All of you need to get your minds out of the gutter; that is disgusting. A dirty sanchez is simply when one sticks their finger into one's own butthole and then puts it into another person's ear, using a twisting motion similiar to that of a wet willy. So there!
After I gave my friend a dirty sanchez, I made sure to wash my hands well.
