Current slang associations underline the fact that, for some, the idea of being called a bitch is just as derogatory as ever. Bikers "ride bitch" (pillion), but only when their own bike is unavailable, of course. Among heroin users, the major artery for injection is known as "your bitch", hence the Prodigy's most famous track Smack My Bitch Up. That small, unattractive tuft of hair that some men like to grow beneath their lower lip is also known as a bitch, presumably because of its vague resemblance to female genitalia.

I think we should find out where she lives and smack the bitch up.
