The most versatile phrase imaginable. The meaning of "it's bitches" is completely dependent upon the inflection with which it is said. For instant, if you are are frustrated and someone asks you how your work is coming, you may respond angrily, "It's bitches." This tells them that you are unhappy. Alternately, if someone asks you how you like your new car, you my respond excitedly, "It's bitches!!!" meaning that you love it.

Some would argue that the ambiguity of this phrase makes it extremely unwieldy and confusing and ultimately pointless. This argument is bitches >:(

A casual invitation / threat used by an individual that is not afraid of fucking someone up.
