Whiskey, esp raw or corn whiskey
[1920s+; because it has a kick like a donkey]
I have never seen such a look of surprise on any living creature's face as was on that donk's.
We noticed them in a "donk" (a hollow place) thickly covered with trees and bushes, but not before we were right amongst them.
I managed, however, to get the duck; the donk got the ducking.
But instead of being dead the box of tricks ups and gives the donk another butt and moves on.
Next day Coonskin was the most embarrassed fellow that ever rode a donk.
