What does ride the goat mean in freemasonry?

The phrase "Ride the Goat" is actually based on a misreading of an acronym used by Freemasons. The Supreme Being, having many names in the different religions of the world, is referred to by Masons as the "Great Architect of the Universe", abbreviated G.A.O.T.U. . You can readily see how the Word "goat" is derived from this abbreviation.
