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.

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.
