It's huckle*bearer.* Everyone thinks Doc Holiday is saying berry because his accent drops the last syllable of the word, and their brains fill it in as berry because they don't know that a huckle is the handle of a casket, and that he's saying huckle*bearer*, as in, *he will carry your fucking casket at your funeral.* Suddenly him saying *"I'm your hucklebearer"* every time there's a call to violence makes much more sense, doesn't it?
