a sex-move that backfired: when you punch a big round rubbery ass so hard that your fist flies back and hits you in the face, leaving a hoof-like imprint over your eyes and nose, or mouth
"Bro what happened to your face - that looks like a hoof-print!"
"...aaah, it's a long story."
"you got badonkey punched? amazeballs"
Buy a
badonkey punch
mug!
An ass so big, round and perfect that it's just off the scale, to the point of being ridiculous. And/or any flagrant action performed by somebody in possession of such a badonk, especially when the action features said badonk.
Man did you see that Nicki Minaj new video? Badonkulous!
