shit for brains

Something that all most all rappers possess. In the rest of the general population this quality in exhibited rarely. Yet among rappers it all most if not entirely 100%.

I don't know how they got so many idiots in one genera. Usually they are spread out, one to a village.

The best, most socially conscious thing that they SHOULD DO is not breed. Although it seems that all they really care about is acting and dressing retarded and getting their peter wet.

That rapper has the brownest eyes I've ever seen. He must have shit for brains !!!
