This is a term black Caribbeans use to malign other black caribbeans whose skin color isn't black enough. My favorite reggae performer is Yellowman. He's an albino Jamaican.
Why it is used to malign east asians is beyond me. Why oriental is racist is beyond me. Just goes to show the absolute intellectual and logical bankruptcy of the people who push this thought policing. "Person of color" = dignified "Colored person"= RACIST!!!
Maybe the next newspeak edition will have an appendix to clear all this up?
