How do kids talk nowadays?

[draigwen]

I'm writing a story for an assignment that needs to be handed in on the 6th, and I've realised I'm stuck. The story is from the point of view of a British 15/16 year old boy - a bit of a thug. And now I'm getting stuck on language. Things started off well, but as I've carried on wrting I'm finding that my knowledge of how kids talk (except for using the 'F' word) is causing me difficulties. Does anyone have any good suggestions, or know some good resources I could use?
