White girls who think they are black.
See Grey Guys .

They portray what they believe is an accurate depiction of what is considered black. They really think they are soulful, but they have names like Ashley and Tiffany and can turn their 'blackness' on and off when it behooves them.
Grey Girl: "Aye, whassup gurrrrrrrrl? You seen my baby daddy?"
Other Grey Girl: "Naw but I heard Day-Day tellin this other hoe that she had seen him up in that hoodrat's house in the Cliff"
Grey Girl: (while moving her head back and forth in a very exaggerated manner) "OH HELL NAW. Where she stay?"

Grey Girls make me want to slap the taste out their mouths.....
