All get out
"All get out". I believe has its origins in the idiomatic use of the word "ought" - as in 'duty' or 'what's coming to me'. Northern England: "I took out this bird, 'til I realized I wouldn't get ought from her".
I probably did not sufficiently emphasize how familiar the first usage is in the U.S., where it is as common as all get-out.
