They call it "Jewish Christmas": Chinese food and a movie.
I suppose, then, that Witches' Christmas would be Indian food and a movie.
I don't know what it is about witches and Indian, but there sure does seem to be something. No doubt there are individual Jews who don't do Chinese (overexposure as children, probably), and doubtless there are witches out there who don't relish alu gobi.
But bring some palak panir to your next coven potluck and then tell me I'm wrong.
