Just as "crone" has been embraced as a positive in a certain context, other perjorative terms have been turned to positive use. "Bitch" can be so used, as can "nigger." Importantly, the rules of usage require that the person using the term be of the class to which it is normally perjoratively applied. I have used "bitch" affectionately with close female friends, but I would never use "nigger" in any context other than an academic discussion such as this.

Hmmmm. "Bitch" is also an animal term. I have also heard "sow" and "cow" negatively applied to a woman. And, "hen," although that usually carries a connotation of fussy benevolence. And let's not forget "vixen."
