Clues or Indicators that a White chick is open to BBC

A lot of white guys have posted threads about finding white women who are into BBC. It's obviously a long shot in real life, but I was wondering if any experienced people here can think of any clues or indicators that a white woman might eventually be open to the idea of this lifestyle or BBC? Just looking for realisitic things that might put the odds in your favor of finding a white woman who is into this.
And I'm not talking about super explicit ones either such as bbc anklets, or spades tattoos.
I was thinking obviously that a white chick into rap or watching basketball would be a good indicator. Also heard that women into smoking pot might be another one.
Any other ideas?
