The Musky Dutchman
This is a close relative to "The Dutch Oven". It is a vile sex act in which a girl (or a guy depending on your sex or sexual orientation) swallows a fart while giving you a rim-job.
Hey, do you remember that girl I picked up at the bar last night? Well, she was rimming me and I gave her The Musky Dutchman and she held it like a bong hit!
