This is a sex position requiring at least two men, and another worthy participant.
Man A gives Man B a reach-around (meaning Man A puts his penis in Man B's butt as Man B has his back to Man A)
and as Man B's penis is spinning like a dutch windmill in a hurricane, Man/Woman C puts her face right into the line of fire...leaving a giant mushroom tattoo in the facial region.
And she is now left with "The Dutch Windmill" on her face.
Frat Bro: "Dude, what happened to your face?"
Your sister: "Shit. I got smashed yesterday, and I must have gotten "The Dutch Windmill"
