The Armpit Dancer, so named because the dancers are literally and factually in each other’s armpits, and spend their entire dance in each other’s armpits! They start out in front of each other (sometimes, which is where it is most advantageous for each partner to be) but then for a variety of reasons (mostly turns, ochos, and crosses, not to mention habit), they end up in each other’s armpits! There’s much longer article on this topic that you should go take a look at and it has a really wonderful video that explains this issue in great detail. This video is free > The Arm Pit Dancer.
