Paul Kerswill, professor of sociolinguistics at Lancaster University, is studying street language in London. He says an entirely new dialect is emerging.
"Young people are growing up with a new form of composite language. It's a bit cockney, a bit West Indian, a bit West African, with some Bangladeshi and Kuwaiti - and it seems to be replacing traditional cockney."

...To illustrate the differences we gave the same phrase to children in different parts of the country and ask how they would say it in their own slang.
The phrase we chose was: "John's girlfriend is really pretty. But she got mad with him the other day because he wanted to hang out with his friends rather than take her to the cinema. She got really angry and stormed off. It was very funny."
Now see how the phrase was regurgitated in the local vernacular in five schools.
