1. n. In the sport of Hoss-Toss, at any time a player can attempt a Gray Hoss, which is a Hoss from the Gray Dot. If successful, the player automatically becomes the Ultimate Champion of Hoss-Toss and noone can ever be considered as good as him. The sport of Hoss-Toss ends when this happens. A player can only attempt this once in his career, and if he scores a Negative Hoss, is banned from the sport for life.
Some people consider the concept of the Gray Hoss to be myth but it is indeed real.
