I recently read this, and while I may have heard it before, it's not deeply familiar to me, if you know what I mean.
I get from context that it means to leave abruptly.
What I'd like to understand is what the metaphor derives from. I find the origins of idioms absolutely fascinating, and I'm wondering about this one. Thoughts?
(I love "shot my wad," for example, the origins of which I learned in a most embarrassing way during a grad seminar.)
