An antolabelist is someone who doesn't like being identified to a common sterotype. A person like this can get easily annoyed by labelers and chavs. They like to make their own personal statements of individualist, as they like being different to the main trend of society.
Antilabelist: "That burbery hat is so weird. It makes you look like a chav"
Friend: "Hey! Im not a chav. Have you got a problem wth me being different from you!?"
