An organ in the body doctors have yet to find. It's function is to store the products expelled during a good puke. It is filled with sausage, peppers, tomato skins, ziti's, meat chunks and various alcohol type fluids such as beer and vodka. The organ assures that you will have a productive puke when you drink a little too much and not just have the dry heaves.
Let me go to the buffet to eat something to refill my puke organ.
