The chav is normally a class of people below working class, i.e classless if you like. They have no money of their own as they get all of this from the government.. how nice of them. Getting payed to do nothing, and incentive to have many many offspring - as they get even more money for this. And, free housing.
The chav father is typically 12 - 17 years of age , towards their early 20's they will have roughly 10 chilren of whom all have different mothers.
The same applies to the chav mother except she will have 10 children of different fathers! this is how they are planning to take over the world - OVERBREEDING.
All chavs have to wear "uniform" if they want to be a part of the gang, if they do not conform to this "cult like" demands of the leaders they will be extradited until they learn to do as all others do. Typically, they all wear imitation sports clothes, a favourite look is to tuck ones socks into ones trousers, possibly to intimidate passers by.
One of the favourite habits of the chav is to hang around shopping centres near argos and "maccy'dees" as they like to call it. They feel that they are very scary, often calling out swear words and insults that would not impress three yr olds. "oi spekkie" , "haha t**t you've got a tie on" . yet when confronted they usually run away, if not they just cowar!
lastly they have built their own language from base english, most words are less than 2 sylables long so as not to confuse each other. not that they would know what longer words meant anyway as most drop out of school at 11.
