Since when I'm prompting, I sometimes just say "right shoulder" (or "left shoulder" for a left shoulder gypsy), I'm going to try using that as the name the next time I call. The teaching would look like:
"Point your right shoulder at your neighbor and look them in the eyes. Walk around them. Swing."
or
"This neighbor allemande right once and a half. Go on to the next neighbor with a left shoulder - point your left shoulder at them, look them in the eyes, and walk around once, but come back to your first neighbor and swing."
(Of course, this means that see-saws are a little bit more confusing, since in teaching them, one often uses the words "left shoulder". But those are rare enough that I'm not overly concerned.)
