I have used it...to great effect.

In the sense of "white culture" essentially being comprised of getting bored, going exploring, finding and taking what we like by any means necessary and claiming that we somehow invented or perfected whatever we stole. Kinda sounds like current Microsoft product development initiatives, don't it? ^_^

As with all things, it can be used for good or evil. I used it when a friend of mine (who happened to be Native) joked that for my birthday, he'd return something he'd borrowed ages before. I laughed and said "Hey, thanks! That's really white of you, thanks very much." Hardly anyone in the group heard the last three words they were laughing so hard.
