Nihilism isn't really a philosophy as much as it's an absence of philosophy. The idea of that creating a kind of random deviant behavior isn't really that unusual. There's lots of different kinds of nihilism as well. You can say someone is linguistic nihilist if they twist words to mean whatever suits their other interests. You can say someone is a meta-ethical nihilist if they reject the idea of global moral truth but still adhere to a localized moral behavior. You can call someone a metaphysical nihilist if they are unconcerned with the nature of their own being but still don't want to get hit in the face.
