Cousin to the famed Dirty Sanchez, this excrement mustache is composed of diarrhea for a fashionable, modern look. Having liquid properties, the mustache tends to flow around the edges of the lips, the leaks creating a nice handlebar stache.
I Filthy Ramirez'd Julie last night and my stache resembled Paco's!
