Don't know if this one is here because I haven't read all the posts but, my Yorkshireman Dad used to say when he wasn't happy with someone - "Well, I hope all your rabbits die".
I asked him what he meant and he said that "in the old days", apparently there were a lot of backyard rabbit farmers, or, maybe, trappers, which were their only income, and to say that was to bring ill to them.
