Drakeo probably got this idea from Mac Dre, an earlier California rapper who also recorded an album from prison. Drakeo talks about Mac Dre in his lyrics and both share some stylistic tendencies like creating their own lingo.
Mac Dre got a lot of respect due to his refusal to inform on the others (even though supposedly he had nothing to do with it). Sad story. He died in a car which was shot at after a show. Very ahead of his time musically.
