The diahhrea version of a dirty sanchez. Having someone with loose bowels create a thin line above the upper lip.
Theresa is certainly kinky, she enjoys getting a Montezuma's mustache every time her partner gets the trots.

A fond relative to the dirty sanchez, Cleveland steamers, and our multicultural favorite, the butthole bindi, a montezuma's mustache only works occasionally, thus it is much more special. When faced with a case of diarrhea, one gently crouches over his or her lover and lets it rip.
Baby, the only thing good about this food poisoning is the fact that we can share our love with a montezuma's mustache.
