Dutch Water Wheel
A combination of a dutch windmill and soggy biscuit, where each man in the circle holds his penis with his right hand, puts his left hand on the man to his left's right wrist and makes him masturbate. They all ejaculate onto a stroopwafel, and the person on the right of the last man to ejaculate must eat the stroopwafel.
Simon - "Let's get some friends round and we can have a Dutch Water Wheel!"
Findlay - "We'll need at least four guys."
