But he (Pac) doesn't get to redefine the meaning or origin of the word. It has way too much history rooted in pretty much all the things we associate with thuggish behavior.

He was at point in his life the definition of such and that's ok. He also grew and learned from that behavior but the nature of that behavior is still what it has always been-- it can't really be redefined as something relatively benign.

I guess what I'm saying is Bieber may have at times acted thug-like but never led a thug life.
