A Dirty Sanchez is a Sexual act that is usually performed by White people typically Trailer trash. It is when a couple of the same or opposite sex engage in anal sex and the one who is giving it to the other in the ass will either take either his shit covered Dick or finger and make a shit mustache then calling it a dirty Sanchez because from a Caucasian point of view it might resemble a thin wispy Hispanic mustache.
Chad and Lance were butt fucking each other all night long. Chad enjoys the smell of shit so he asked Lance if he can please give him a Dirty Sanchez.

A Dirty Sanchez is when the man cums in the asshole and then takes the cum out with his finger and makes a mustache on the females face.

A dirty sanchez occurs when a male places both pinky fingers together and inserts them into the female anal cavity. Once the pinkies have been removed, ass pounding ensues and a reach around occurs. Any fecal remnants are smudged above the upper lip which creates a mustache of sorts.
Since my lady friend is such a big fan of anal sex I felt it would be a great idea to give her a dirty sanchez.
