I’ll give you a hint. It rhymes with witch.
It’s pretty common in prison though, nothing special.
The problem with your suggestion is most female dogs are wonderful,loyal,loving creatures who produce equally wonderful offspring, two of whom are with me right now. Using that word to describe the utterly evil, murdering, lying, thieving Witch is a horrible insult to all dogs. My deep love for dogs is why I have never called that evil thing a bitch.
