A word, phrase, picture, symbol, definition, clothing, genre, subculture, etc that has been marketed by hot topic brand stores origianlly favoured by the people of certain subcultures, leading to over-use of the word, phrase, thing, idea, clique, etc so that anyone can think that they are of the subculture by buying that item. The item therefore becomes abused and is eventually abandoned by the original subculturists but still remains as a sterotypical symbol of the subculture, later being a source of quick mockery or use by posers.
"You laugh at me because I'm different; I laugh because you are all the same!"
