Unplayable Ball - The rules of golf make the player "the sole judge" of whether his or her ball is unplayable, and most players use this judicial power to waive the usual penalty for moving the ball in light of their standing in the community.

Up and Down - Holing out from off the green in two strokes: an approach shot and a single putt. It is more common for players to go "up, across, beyond, next to, around and down" or "up, way over, under, into, through, along, onto, beside and down."

U.S.P.G.A. - The United States Professional Golf Association, which is responsible for drafting and enforcing regulations in America.
