The sexual act that involves a
small person.
If a man inserts his fully-stiffed penis into
small person's anus/vagina, he can start to rotate the small person around his penis, thus imitating the act of turning the sailboard wheel - giving him an
unique grinding sensual pleasure.
Rotation can be also invoked by slapping the small person really really hard.
Man and his wife fighting: "You bitch, if you were a
midget, I'd
slap your ugly face so hard, I would be
midget sailing till next Tuesday!"
