Derived from Chatham in Kent, this term can be applied loosely to every culture with a nasty, thieving element. There are many variants of this creature but all are subject to the following commonalities:
Chavs are completely Amoral, having never been subjected to right and wrong by their inattentive, uncaring and often absent parents.
Chavs are part Magpie, evidentially supported by their love of all things shiny, or as vaccuous, illiterate street-slang would say 'Bling'. They can be seen twokking from the Jewelry counter in Argos/Index.
Whatever their ethnic background, Chavs have a built-in affinity to hip-hop/R&B, even if they are inherently racist (see the Scottish). They see their life as glamorous and cool.
Chavs are for the most part, extremely stupid. However, some of them render a form of low cunning, which can be misinterpreted as intelligence. However this is false. A Chav has no desire to better themself through honest means nor learn anything outside of car modification.
All chavs think that they are nails. Again, this is false. Sitting in a beaten up nova smoking lamberts does not precipitate a healthy body. The irony being that a Chav owns mainly sportswear, yet will only break a sweat if running from the police.
Chavs are incredibly fertile beasts, and are highly successful breeders. Where they come unstuck is having to look after the offspring which their 13 yr old drunken fumble produces. More often that not the child will crow to be a Chav, having received no more guidance on life than the parent.
Chavs have a fond love for cars, as well as a Vin Diesel fixation. Rather than buy a nice car to start with, a chav will spend all their dole and tax-free labouring cash on upgrading a 10 year old car with 200,000 miles on the clock. The end product will invariably be a luminous monstrosity with at least one serious collision to it's name.
