"wigger"

I can't remember where I heard it now, but a radio interview between Tim Westwood and Eminem, each unable to understand the other's pseudo-black argot, was once aptly described as "the pot calling the kettle white".

I've never heard of neds, which probably means it's neither Mancunian nor Cambridge slang. Could it be short for [censored]in' [censored]-'eds?
