First of all, I'd like to make a disclaim that I'm not into white girls. Believe it or not, I much prefer Asian females.
She said that: a white girl is usually attracted to a non-caucasion male who's _sporty_ and _muscular_. I know she's a girl of typical tastes towards men.
My understanding is that they're not into the so-called "cute" and "handsome" boys. So make sure you look more like Mike Tyson instead of Will Smith, never look like Jet Lee if you're after caucasions.
Good luck to the caucasion girl lovers. Wish yall have a white Christmas...
