It's been a lot of fun educating my US colleagues on the use of the term chavtastic and it's catching on!
What is a chav? Its generally a term we use to describe young people who speak incorrectly, wear baseball hats 24/7 (not common attire on the streets of Britain), fake sports tracksuits and extremely large white trainers (gym shoes). The girls, often referred to as chavettes, are known for sporting big hair, even bigger earrings and Mr T like jewellery. They have also been known to affect the teenage pregnancy stats. Think of MTVs 16 and pregnant with a little more bling. You'll generally find them hanging around on street corners appearing more menacing than they really are. And some, not all, will find themselves in trouble with the law at some time.
Vicky Pollard is a fictional character in a TV show called Little Britain and she is the extreme version of the chavette. She has been around a while but this is still a classic chav performance:
So next time you think something is 'trashy' try out 'chavtastic'. It's just a cool word!
