Phenomenon in which your shit 'corks' itself. When you first start taking a corker, the begining is like a regularpoop, but after you've passed an inch or so, the rest squirts -- you've uncorked your bowels.
A corker is a lady who masturbates with a bottle of sparking wine. Part of the thrill is the danger of the cork popping before orgasm and causing damage.
