A B-stache belongs to anyone sporting a moustache reminiscent of a stache found in a B-movie, especially an 80's B-movie. The bestowing of a B-stache is often enhanced by naming a specific B-movie or B-movie actor that the B-stache most closely brings to mind.
Did you see that guy? That was a Smokey and the Bandit B-stache!
