mex-stache 

The untrimmed mustache that makes you look like a dirty Mexican.

Tondo didn't shave for a week.
As a result, his friends crowned him Mr. Mex-stache of the month.

Mehstache 

Any moustache produced by someone below the age of 20. They try to make it look like a real moustache, but it's really just meh.

That kid should just shave, his mehstache is impressing nobody.

mexostache 

A mexican mustache. That trails from the center of your upper lip, to the mountainous region of the asshole. Can start at the anus. Genererates 300kohms of butt-crack-heat in less than a second. They are stylish on men, but do not look good on women, unless they are Russian, but they are pretty much men anyways.....

I shaved my mexostache today because I got tired of keeping it up. The powerful shocks to my nutsack did not help either.
