It shows how retarded they are because they don't even know the real meaning of the word. Someone might come here and tell you that g-money stems from gun money - the money paid to a hired thug who is proficient with small firearms. In fact, g-money originates from the term 'good money', which is a term used by White, Angelo-Saxon Protestants (sometimes called wasps). Good money is redneck slang for a lucrative deal, to make a good amount of money for doing the least amount of work that they possibly can. This is a term that originated on the plantation, a way for white plantation owners to talk about slavery without using such a negative word.
Any American of African decent that willfully goes by the term G-money is in fact promoting slavery, an Uncle Tom if you will.
Present: Yo, g-money, you is the shizznit.
Translation: Hey, good money, you're making the Man a lot of money.
