Dutch Windmill

When two people sit face to face, one on the others lap and defecate into the toilet basin at the same time, legs spread in all four directions forming a windmill.

“Hey Gaz are you going to be long in there, I’m touching cloth here mate?”
“Sorry buddy I’m having a real battle with this one, I’ll be a while yet, but feel free to come on in and Dutch windmill with me if you can’t wait any longer.
