Yah to me it always looked fun like playing slip-and-slide, twister, or some other 1970s Milton Bradley game.

Your explanation of it being a form of humiliation makes me see why it could be a kink for some people.

Personally, I'm not into feeling humiliated, but I find many of the activities in kink circles that are designed to induce that to be fun or kinky. I guess if the domme was a humilatrix she wouldn't get much out of it as she wouldn't see those emotions in my face. Sort of like a sadist wearing her arms out hitting someone who doesn't make a peep.
