A sarcastic phrase used to designate a snobbish attitude, or describe people who take themselves too seriously. A play on "'holier than thou." Someone with a "more gothic than thou" attitude will likely tell you about the gothic bands they are into by saying, "You probably haven't heard of them."
Because her whole house was painted black, it gave her a "more gothic than thou" attitude.
