Someone who believes they deserve the stars because they like something no one else likes, or does something no one else does. There is no know cure for SSS (Special Snowflake Syndrome), so the rest of the world must deal with these sort of people until they realize they aren't better than anyone else, and they don't need an award or a cookie for their interests. Not to be confused with a hipster.
A special snowflake: "I liked My Chemical Romance before Three Cheers For Sweet Revenge! Love me."
