Yeah, neds, chavs, townies. All the same.
(Ned incidentally stands for non-educated deliquent)
They basically look the above and partake in drinking the cheapest cider avaliable (I believe Sainsburys is offering 26p a pint) - drinking it as fast as they can on a park bench while listening to some piss poor garage on their mobile phone. Once nicely pissed up, they will go out looking for a fight, preferably 10 or more of them on one or two innocent bystanders. They all think they are gangsters but tend to live in former industrial and market towns. The female equivlant will be pregnant by the time she's thirteen and will be living in a council house with her chav boyfriend by the time they are 18, where they can take as many ecstasy pills as their dole money can afford them. You can recognize them by their fake burberry hats at a 45 degree angle and trackie bottoms tucked into their socks.
If you ever come to England, watch out for them. They probably like beating American tourists especially. Rant over.
