When a woman from Amsterdam forces her male partner to insert a cork into his rectum before any intercourse has taken place. Upon climax, she removes the cork, causing an expulsion of 2 bodily fluids at the same time. This is often followed by the woman rolling around in the male's feces/semen mixture and pleasuring herself.
Ian's friend Dan had the bottle opener performed on him for the first time unwittingly while visiting Amsterdam.
