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.

Dirty Sánchez describes the practice, in which the active partner, immediately following ejaculation, inserts the finger into the anus of the passive partner and then smears a mixture of semen and feces under the nose of the passive partner. Eventually, the finger is then licked off by both partners. The naming was chosen, because this was to evoke the impression of a "Mexican moustache."
