Mulligan - A second, provisional ball played following a tee shot that may be lost or unplayable. If the first ball is indeed lost or unplayable, the "Mulligan" is then played with a one-stroke penalty. If the provisional ball is played, but the player forgets or declines to add the penalty stroke to his or her score, it's a "Haldeman." If the player finds the original ball in a playable but inconvenient position, surreptitiously pockets it and plays the provisional ball, again without penalty, it's an "Ehrlichman." If a player steals a ball from an opponent's bag to play as a provisional ball, then counts neither the stroke used to hit it nor a penalty stroke, it's a "Nixon."
