Total reject, someone who doesnt fit into any group and is outcast not because of individuality its because they have no friends. As a rule they are sad and need to feel like thats exactly what they want people to think of them. They hear all the abuse directed at chavs and have no friends who are chavs so they dont join that category or any other for the same reason. Calling themselves rude is a good description, but not for the reason they think, rude means obnoxious and repugnant which sums them up perfectly.
"Im a ruud" (wtf? spelling rude wrong adds no value)
"You label yourself and follow trends im seperate from groups." (the reason for this being you have no friends and need to give your pathetic worthless life some meaning)
