The stink mustache is the result of a dirty sanchez, manual sanchez or any other form of shit-to-upper-lip application. It is the actual smell carried around just under the nose until some way can be found to clean it off.
Hey man, what's the matter?

That bastard just manual sanchezed me and now I have this Stink Mustache I can't get rid of!
