From this guy I used to go out with.
You don't want to know the details.

Probably from some really pissed off guy who wanted the object of his ire to stop talking and also to eat, or swallow, his/her words. I was really angry once at a loud mouthed idiot and he wouldn't shut up. I grew more and more angry. I had to fight the impulse to grab him by the throat with one hand and ram my fist down his throat to make him stop spewing his hateful words.

I actually just walked away and divorced him soon after. But I still think a situation like this is what started that saying. Don't you?
