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.
