What exactly is a hollaback girl?
People engage in a healthy debate as they try to decipher just what Gwen Stefani is trying to say. But most entries point out that Stefani may have just invented the word and tried to pass it off as real slang.
My theory is that Gwen Stefani wants to become the sort of icon that Madonna was, who went from fishnet stockings to semi-goth to English rose. That's probably why Stefani would go to the extent of importing that Harajuku girl look, but completely missing the point.
