A bitch mouth is any guy who who runs his mouth like a little bitch. This is particularly true in the context of gettin pwned (i.e. getting an ass whoopin form you boy in a game of hoops, you whine and complain like a dirty bitch mouth). In short a male who is whiny and complains excessively. This word can be used as a direct object noun (i.e. he has a bitch mouth) or as an act (i.e. Every time I kick you ass in poker you act like such a dirty bitch mouth).
