1) Have a name that either invokes grotesque imagery or shows how little you give a fuck.
2) Have a band member do a lot of cocaine (applicable to most any 80's band).
3) Sing about epic topics such as dragon slaying, murder, dead gods, or war.
4) Sue Napster.
5) Do charity work, which is cool, but still kinda breaks the whole "we don't give a fuck," image.
6) Gain a reputation as hypersensitive assholes.
