shit your slit

The unpleasant result of an attempted bowel movement while one is gloriously inebriated and sitting on the stool, but while wearing long johns and being too glued up to realize the "slit" was not parted sufficiently to pass the turd, resulting in the movement being accidentally retained in the long johns and causing great ongoing grief amongst friends and famliy alike. Things like this are "why they call him Grodee".
