Immediately after concluding Anal sex with your partner, insert a finger of your choice into your partners Anus. After removing finger, reach around to the mouth area and wipe your finger directly above their lip, applying a "Dirty Sanchez" moustache.

Doing a chick, best when doggy style, and at some point during the act of sex...sticking your finger(s) in her ass, and then rubbing that finger(s) on her upper lip, thus giving her a fecal mustache.

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.
I told the bitch I'd give her a Dirty Sanchez if she wouldnt shut her trap.
