This never happens to you, no doubt, because you are perfection itself.  But if someone were to call you the b-word (they'd have to be crazy, right?), consider replying that yes, you can do that.  If that's what they want.  But that you assume no responsibility for the slapdown they will inevitably take (verbal or otherwise) from you.  And while you're being a bitch, be a well-blinged one, with a piece guaranteed to set the record straight -- like this 22k gold plated chain with silver accents.
