Chav Magnet
I came across the phrase 'chav magnet' while looking through the ChavTowns website (reading all about Crawley)
It seems to be a term which can be applied to cars, shops, pubs, places, bands, objects, in fact just about anything which would attract a following among the chavvier elements of society. (Just do a search and find the variety of uses)
One site which that search turned up was this one - showing that by last December the term was already heard of in Australia.
Chav Magnet might have been a great name for Goldie Looking Chain if they had not already called themselves GLC, otherwise it would be a great name for any band whose first single is released as a limited edition burberry vinyl 7-incher.
They will probably come from Croydon. Or Reading. Or Bromley. Or maybe even from Crawley
