The phrase "on the green" is commonly used in the sport of golf. It refers to the area of the golf course where the grass is trimmed short, allowing players to putt the ball into the hole with precision. Being "on the green" indicates that a player has successfully reached the area closest to the hole, which is crucial for scoring. Players must demonstrate skill and strategy in their putting techniques while on the green to ensure they complete the hole in as few strokes as possible.
