Double M, I got G’s out in California
Ross puns on the name of his label, Maybach Music Group or MMG, suggesting that the Maybach Music folks make money (G’s) and/or know real “g’s” — gangsters — on the West Coast
Double M could also refer to the Mexican Mafia, who are the most powerful gang in the California prison system. These are most likely the G’s he’s talking about.
