1. A form of sport we don't often see or know about, it goes like this: There are two men with a ball on the field, and the one who gets chosen to start throws the ball at the other guy's stomach, trying to make him puke. Then the other man does the same, and this goes on until at least one of them pukes.
2. Canadian vegetable, round and blue. Has been used in the ancient version of the sport batathon, thus the name.
