Here's one of my favorite May-games: a kind of ritualized mock orgy. It's called “Milk-White Pony.”
(I got it from a local Wiccan priest who claims to have learned it at Boy Scout camp. To judge from the stories I've heard, I could well believe this.)
The dance takes place in a circle, with everyone singing and clapping. Here's the verse:
I saw N on his/her pony
riding on a milk-pony
I saw N on his/her pony
and this is what he/she told me
During the singing of the verse, N “rides” around the circle on an imaginary pony. At the end of the verse, the rider stops to face someone in the circle.
Then you sing the chorus:
Front, front, front
O baby
Back, back, back
O baby
Side, side, side
O baby
This is what he/she told me.
Both dancers thrust their pelvises at each other as they do this, front-to-front, back-to-back, or side-to-side as the lyrics call for.
Then N rejoins the circle, whoever he or she danced with hops into the middle, and the game continues.
No doubt the tune is out there somewhere—everything's on Youtube—but if so, I haven't been able to find it yet. I promise to keep looking. Meanwhile, consult your favorite ex-Scout.
Every coven should have one.
