Chav
From Wikipedia:
Charv/Charver (male) and Chavette (female) ('ch' pronounced as in chair) are mainly derogatory slang terms in the United Kingdom for a subcultural stereotype fixated on fashions derived from American hip hop such as imitation gold poorly made jewellery and designer clothing, combined with elements of working class British street fashion. The term appeared in mainstream dictionaries in 2005.
There are regional variations; in the north east of England (particularly in Newcastle and Gateshead), the variant charv or charver/charva is most commonly used and has been used since the early 1990s, while in the south east chav and chavette are the usual forms. What is unusual is that the vowel in charver is ɑ (as in 'far') and the mainstream UK equivalent uses the a (as in 'cat') vowel in chav which goes against the usual North-South (a/ɑ) vowel distinction.
The defining features of the chav clothing is the Burberry pattern (notably a now-discontinued baseball cap) and from a variety of other casual and sportswear brands. Tracksuits, hoodies, track suit bottoms 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 juvenile delinquency, the "ASBO Generation", "Hoodie culture", and "yob culture".
