White guys, when you hear a Black girl talk and she's "Whitewashed" do you take it that she likes White guys?

This is a real question because I always come across Black & Latino guys who say it all of the time. They ume because I am... well, I talk pretty much like a Valley Girl, that I only date White men. Black guys always make jokes about it when I meet them (also because my name is "Becca" lol. smh). So I just want to know. Don't troll and say "White men don't like BW" or w/e because that's not the question, I know many like me, and I'm just wondering now if its mainly because they ume I'd like them back because of my mannerisms??
