Everyone is wrong. A Dirty Sanchez is a slang term for filthy Mexican. Usually this term refers to a male particularly ones named Sanchez, Juan or Pedro. Usually the source or filth is low paying yard work but may also include dirt accumulated at home or in a vehicle due to cramped living conditions in Hispanic households.
Yesterday I saw a bunch of Dirty Sanchezs planting bushes in my neighbors yard.

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.
