Cultural appropriation is a term that isn’t often heard in daily conversation, which means it’s inevitably misunderstood by those who feel attacked by feminists, sociologically-informed bloggers, and others who use the term.
A further (recent) illustration on what cultural appropriation is would be Ms Mindy, who calls herself the "warrior princes" (who makes Xena roll over in her fictional grave, even though Xena herself engaged in her share of appropriation), but then the Maasai version - despite being white, middle class, American, and very very privileged.
