"Don't be prang; be nang. And use slang. Bang bang" as the lyrics to my latest release on BaldNinjaRecordings go. Not really*
But "nang slang"- one of the names given to the youth slang influenced by Bangladeshi young people in east London - is covered in real depth in this programme from the BBC Asian Network. If you can get past the first couple of minutes of rather self-conscious attempts at uber-hipness, it's a really good programme, with guest appearances by Tony Thorne (who'll be one of the speakers at our English Language Workshops for teachers in June) and Sue Fox (who spoke about her research into this dialect at our last student conference) among others.
Thanks to my bredren Tony C, aka MC Fruityloops, for this link.

*I have to say this because I told one class last year that the linguist Pamela Fishman was half man half fish and several students believed me.
