From the Appalachian region of the US, I bring you:
“I’ll cut the blood out of you!”
and more generally within the US (I think?):
“I’ll clean your clock!”

Both are threatening a fight, one a little more graphically than the other. I don’t think I’ve heard either in a very long time, and it was only ever from my grandmother that I’d heard the first phrase. Not directly, as in discussing idioms.
