It is a dance step. Commonly associated with the square dance, however the step is also used in other dances. Actually I was thinking about the dance of the compass and the square upon the holy books. If you get the point. Me thinks that the the compass is just an articulating square if you will. Formed of the rib, as in a curve. If a man is the angle, yes men have an angle, only some of them are square. Then the she is articulating. In the end, we eventually know who comes out on top. If we attain wisdom, dancing upon the holy books. Articulation is the creator.
