In “standard” ballroom dancing (which means the non-latin dances of waltz, tango, viennese waltz, foxtrot, and quickstep):
Feathering - an action characteristic of the foxtrot, where both members of the couple stretch their left sides forward during the rise action at the middle of the measure
Promenade - both partners look and move in the direction of their joined hands (leader’s left, follower’s right)
Counterpromenade - both partners look and move away from the direction of their joined hands (much more difficult than promenade)
Heel turn - follower steps back and turns balanced on her heels, while leader steps forward and around her (characteristic of international foxtrot, but appears in waltz and quickstep, as well)
Natural - right turning
Reverse - left turning
Contra-body motion (CBM) - “twisting” action where body rotates against alignment of feet (e.g., right side moving forward while stepping back on right foot)
Contra-body motion position (CBMP) - a position sometimes (but not always) achieved during CBM, where the body and hips are rotated contrary to the foot position
Swing - action of the hips and feet producing a free, pendulum-type action of the body (not to be confused with the dance of the same name - the “swing dances” are waltz, foxtrot, quickstep, and viennese waltz, but not tango, which does not have any swing or sway)
Sway - inclination of the bodies away from the feet; should be produced by swinging action across the floor
Tipsy - quickstep figure where body sway changes “over” the feet instead of under to produce a wobbling action (also knows as metronome swing to distinguish it from the more common pendulum swing)
There are many, many more specialized vocabulary words and phrases, of course.
