I think the song is about drug use, and his friends critizing his drug use, while being hypocritical. They act dirty, meaning they use drugs also, but they keep themselves so clean -- as in, they keep their reputations clean, so they can still be judgemental. "I'll hold the sky" or "in the sky" is often a drug reference.
