When a male ejaculates onto their partner's face (generally after oral sex) and the semen lands largely on the upper lip. The ejaculatee then puts on a sombrero and yells "Dios mio!" and restrains their partner until the semen dries, creating a queso mustache.

A Chicago Mustache is similar to a Dirty Sanchez, except the person giving the Chicago Mustache eats nothing but laxatives and corn the day before and proceeds to spray loose, chunky shit all over the face and upper torso of the person receiving it. Similar to a Manitoba Milkbag.
"Ryan was sleeping one night and I gave him a Chicago Mustache. There was corn everywhere."
"Bitch got mouthy, so she got a Chicago Mustache."

The result of sucking on a milf's breats after she has had a baby. Similar to the Milk Mustache but much classier.

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.

The particles of shit crumbs and ass matter that stick to the freshly laid strip o'jizz on a whore's upper lip after someone farts in her face.
