g-money
G-money has entered in as a popular nick name amongst want-to-be gansters.  It showed up in the 80s amongst their version of hip-hop music/rap and became more popular in the 90s by older want-to-be gangsters.  It should be noted that the older want-to-be gangsters wanted the world to think old was cool again, so they also invented old skool.  So, finally some cats started calling themselves G-money.  When someone starts using a slang word as their nickname, its a sign that they are retarded. 

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.

Translation: Hey, good money, you're making the Man a lot of money.
