The lowest common denomenator of English society, equivalent to white trash
for Americans although with many differences.
The word originates from the embittered attitude of people like myself from being perpetually asked "what yu lookin at?" by an individual dressed up like a cross between a gimp, JJB sports and 50 cent.
Chavs are renowned for their aggressive behaviour, amusing use of the english language, original sense of style and behaviour to society as a whole.
Chavs emerse themselves in a perverted form of a sub-culture: their main music tastes are in drum'n'bass and crap rap. The "female" chavs or Chavettes or Shaza's enjoy r'n'b. They have no apparant interest in literature (lol). In my view their most definitive and humorous attribute is their "use" of the English language, their favourite terms include, "brethren", "rude" and "brrap" (only for the hardcore Chav).
The term "chav" is the commercially utilised form of a notion that has been bouncing around England for years, the specific term being dependant upon location. Popular synonyms include: Pikies, Hood Rats, Kevs, Townies, Neds and many others. The universality of the term if useful in uniting this observation but regrettably depersonalises the word, and also has allowed those whose lives are unaffected by Chavs to pollute and alter the meaning of the term. Because of this it seems inevitable that the term will die out and become a trite cliche.
A chavs attitude to society is one principally shaped by amorality. A Chav feels no sense of "social responsibility" and therefore feels permiited to exploit the wellfare system, mug and beat up strangers. Although it as at this point that the term Chav is shed of its charming innocence and instead tainted with a viscious prejudice, one that assumes the entire populace of the working class consists of Chavs, this suggestion is both moronic and repugnant.
Therefore I believe in order to preserve the dignity and good humour of the term it should only be applied to an individual who firstly demonstrates violence, a true indication of being classless.
The second most substantial threat to the continuation of the term is from the media. The word was formulated through the frustration of adolescents such as myself at being attacked for absolutely no reason (except accidentally and temporarily gazing in the general direction of the individual). And not by some ageing arse-wank journalists trying to revive their long dead and fetid period of being young and cool.
