It started as a word, but it has grown into a phenomenon. The wiki says chavs are:
Chav or Charv/Charver ('ch' pronunced as in chair) is a mainly derogatory slang term in the United Kingdom for a subcultural stereotype fixated on fashions such as gold jewellery and 'designer' clothing. They are generally considered to have no respect for society, and be ignorant or unintelligent. The term appeared in mainstream dictionaries in 2005.

The defining features of the stereotype include clothing in the Burberry pattern (notably a now-discontinued baseball cap) and from a variety of other casual and sportswear brands. Tracksuits, hoodies, sweatpants and baseball caps are particularly associated with this stereotype. Response to the term has ranged from amusement to criticism that it is a new manifestation of classism. The term has also been associated with delinquency, the "ASBO Generation", "Hoodie culture" and "yob culture". Chavs are often stereotyped as being particularly anti-emo and anti-Goth, two other subcultural groups.

If it's tacky, chavy, brassy but not classy, put it here.
