The Rock Life?

I'm doing a little informal research for another article I'm writing and I thought perhaps all of you could help. Tell me, what does it mean to "live the rock life?"

Does it mean dressing a certain way, living in a certain manner, believing certain things? All answers are correct and I suspect we'll get an interesting cross current of information here. Please, feel free to write as much or as little in the comments section. I do thank you for the help.
