As applied to a guy, refers to a man in denial about the fact that however much he likes pussy and the female form in general, he also likes a heapin' helping of the man meat from time to time. However, he will swear up and down that he is absolutely not bi in any way, shape or form, even as he goes to suck your dick with the finesse of a $1000/hour call girl. Poor bastard.
