Who are these bitches, and why are they shopping?

Bitches be shoppin'. Three little words to digest. I'm not even sure what there is digest from them. That somewhere out there, there are bitches who like to be shoppin', I guess? Even I don't know what it really means. Also, it was derived from a very indirect source, of which has no real importance to anyone but me, and maybe a few others. But something about it makes me smile, and I imagine will make someone else smile, fingers crossed. In a sense, it may very well be the answer to all of life's incessant little questions, like how will I ever be able to afford the soaring costs of gasoline? Well, bitches be shoppin'. If only it were so easy.
