Or has that label been lost, because it apparently only describes one particular race according to a few tweeters and forum members.

I'm quite sure the word has been used several times - mainly by Tiffany herself.

But it's different, innit?!

Aisleyne was described as ghetto because she was adhering to the negative black stereotypes associated with that word. Do you see the difference? Aisleyne is a disingenious person who played up to being a black stereotype. She wasn't simply a mouthy woman. The word ghetto specifically ties 'black' to a set of negative connotations. Since black people have had a history of facing prejudice and discrimination based on being 'lesser than white', Megan calling Tiffany means a lot more than what you might think.

I'd say 'desperate' fits her better

Standing ovation!

People called Aisleyne a "wigger".

Yes Yes Yes Yes Yes

It is different! If I use a word that is commonly used as a slur against my sexuality/ethnic group about myself in a non serious context it is VERY different then if someone else calls me it when they're angry.
