Ain't had no pot to piss in, now my kitchen full of dishes
He used to be piss poor and was cooking up drugs for a living. With this, his sink was full of dirty dishes. He’s implying how poor he once was.
Not having a “pot to piss in” is an old, Northern English phrase used to express how poor someone was (so poor as to not be able to afford a toilet) or simply to imply that you had nothing, whether in terms of materialistic possessions or future prospects. Rocky’s saying that he was once poor and didn’t metaphorically “have a pot to piss in” and now that he has money, his kitchen is full of pots and dishes and he now has a lot of money, although he still apparently hasn’t learned that the porcelain throne is, by this point, a much preferable alternative to pissing in woks and the like. Hygiene and all that shit.
You can take the boy out the hood…
