An expression used by chav
s to express their hatred for anyone with an IQ higher than 20. Hanging around in groups of at least five, they wait around street corners eating Maccy D's
all day until one of them plucks up the courage to shout to a stranger "Get a haircut, hippie!". This will often be followed by any kind of comeback, witty or not, of which the chav
will be unable to reply.
