For me "Rockstar" is now a shibboleth.
If you have to call yourself, your company, your product or your programmers "rockstars" then none of you are real rockstars. If you have to ask "what's different about rockstar's lifestyles compared to the small people?" then you definitely have no idea what you're even talking about.
It's just like being called a "hacker", or a "gangster" or similar. You either have legit street cred, and thereby are automatically included amongst an elite, meritocratic subculture, or you don't.
