The etymological history of the term "Dirty Sanchez" originated with one Generalissimo Leopoldo Sanchez, who led the infamous and ill-fated raid on the Panoche Grande brothel in 1848. Mistakenly believing he was counter-attacking to fend off an American incursion, he resigned himself to a life of tequila and debauchery in the alleys of Juarez. He was known for sporting a excrement mustache and a large silver-toothed smile.

The real dirty sanchez is when after lovingly cuming in your girl's ass you insert your finger in her pooper and remove cum mix with poop and place it carefully on the upper lip of your loved 1 looking like a well drawn mexican mustache, also known as a "DIRTY PIER" in europe for the resemblance to a french mustache "Pier" and cause they stink, but; almost always welcome when is tastily done.

A time honored event in which, while laying the bone doggy-style, you insert two fingers deep into the girl’s starfish. Pull it out, then reach around and wipe the residue across her upper lip, leaving her a thin, shit mustache. Making her resemble someone who would be called Dirty Sanchez.
