From the mouths of teens

This article is based upon the slang words used by teenagers living in the inner zones of London and the journalists within this article want to understand how or why the words used by teens have developed to become such a normal part of their vocabulary. The article further explains how teen language in London is spreading all over the UK. 

The researchers have found out that the dialect used by teens is very similar to the words spoken by people from a Jamaican/Afro-Caribbean background, for example many use the word 'sket' which originates from Jamaica and is often used as a slang word to describe a girl as a slag. Therefore because of this they describe the language used in London as MLE (Multicultural London English) as the cultures in the city are beginning to blend as one. 

Why do teens speak almost in their own language? Social class, fashion, music and ethnicity are said by this article to contribute to teenagers expressing themselves and so say keeping 'cool', therefore a 'cool' dialect would need to follow; one they may not want adults to understand.
