I don't know the whole quote,but I know that part of it is something like:
some kids are pickin' up Thug Life and claiming it as there own,its just a fad and he'll give it up soon enough but I'm doing it for the kid that really lives the Thug Life and feels like its hopeless
Basically he was saying that some of the more suburban kids or white kids that are influenced by it is an unintended consequence of his music but he feels like he wants to give hope to the kids really living Thug Life and the other kids will grow out of their phase in that they think "Thug Life" is cool
