There is evidence of some middle class aping the chavs, hence the rise of Estuary English. My time at uni here was while chav culture was on the rise. The uni attracts a ridiculously large proportion of upper middle class kids (yes, friends of Prince William were in my year) and in first year they were still all Yahs, long scarves, ethnic beads, flicky hair and moth eaten jumpers -shabby chic that you have to be rich to get away with. By 4th year however there was a notable difference in the first year intake with a lot of fake tan, pram-face (tight blonde pony tails) and high street fashion on the kids from Marlborough, Cheltenham Ladies and Ampleforth.
Chavitis seems infectious.
