The Slippery Penguin

This is a sexual position which can only be performed in an ice-rink.

The female sits with her legs apart on the ice whilst the male runs and slides along the ice on his knees and enters his partner.

Male:

"There's an ice rink opening tonight in our town, do you want to go down late and attempt the slippery penguin?"

Female:
"Why not? YOLO!"
