Ever eat large quantities of horrible greasy pizza and drank too much milk and wine and then passed out and heaved on yourself and then thought you were blind because there was vomit on your glasses? It has that sort of old vomit taste. It's all the down side of vomiting with none of the fun (you know; checking for distance, chunkiness, seeing if you sprayed a friend or the side of his car, waiting till you get to the mailbox of that turd breath down the street and seeing if you can fill it up...)
