A Dirty Sanchez is a sexual situation where a man is laying some pipe doggy-style, and while in the midst of sex he inserts his finger in the womans starfish and then smears his finger across her upper lip, giving her a thin shit moustache. This is the Dirty Sanchez.

a dirty sanchez is when you have anal sex and then smear the remaining feces onto your partners upper lip, like a mustache.
I tapped some freaky booty last night, she was so freaky she wanted me to give her the dirty sanchez.
