The ball must thus land in the cup, on the fly, either from the tee or a sand trap, or another surface that is not grass, such as pine needles or clay. If this is the case, the player may claim to have earned a "dunzee" which is among the rarest accomplishments in golf.
A dunzee holds no significance other than to mark an exceptionally bizarre occurrence.
The origin of the "dunzee" is believed to be the first documented account of the feat during a tournament in Pittsburgh, PA in the early 1980s. The late, Donald Dunzee Wolff, Jr., a local golf icon, managed to win a tournament while hitting his tee shot into a fairway bunker, his second shot into a greenside bunker, and his third shot into the cup, on the fly. It earned him a birdie, but the means by which he did it was quickly dubbed a "dunzee."
He had effectively hit his ball over 435 yards, into a cup, without ever touching a blade of grass.
The dunzee is so rare it is almost never seen in tournament play, especially among professionals, for obvious reasons - they are intent of the ball landing in the grass. And even if their ball did land in a bunker, the thought of hitting the cup on the fly is technically a bad shot, though a lucky one. It almost never happens, but when it does, it is referred to as a "dunzee."
