look up any word, like the eiffel tower:
A "Mook's Moon" is when an Irish woman shits on her own face.
Only recorded twice in history, one on Stonehenge, the second "Mook's Moon" was posted by accident on the British Monarchy's offical website. Apparently, George III caught his consort in the act of a Mook's Moon and didn't have his eye on the ball when America revolted.
