The G Code stands for Ghetto Code. It is generally used to describe the old gangsters, the street veterans, who are from the ghetto or the hood as some like to call it. To be born in the G Code is something to be proud of, it means you are a hard-ass gangster and no one can fuck with you.
We don't talk to police, we don't make a peace bond, we don't trust in the judicial system, we shoot guns. We rely on the streets, we do battle in the hood, I was born in the G Code, embedded in my blood.
