They are typically of poorer origin, wear tracksuits, lots of gold jewellery, are guaranteed to wear fake branded clothes. They're favourite drinks are Lambrini for the girls (straight out the bottle, no cups needed) and Cider for the lads, this starts at the age of about 13 and smoking follows several months later. They tend to think they are superior to every one else, hang around in large gangs and cause general problems throughout the UK, such as vandalism and victimize people with weaknesses like being disable or obese.
Unfortunately a new class of 'Wealthy Chavs' are springing up which are very similar except without the fake clothing and they're behaviour is not quite as extreme, they have big houses and nice cars.
