A greenie is when a golfer hits her/his ball onto the green off the tee and finishes the hole at or under par. If more than one player in a group also hits the green off the tee, the golfer with the ball closest to the hole gets the opportunity for the greenie.
A sandie (or sandy) is a bunker shot from a fairway or greenside that is followed by a putt that finds the hole. As is the case with the greenie, if multiple players' balls end up in the same bunker, the closest ball to the pin denotes which golfer gets the first crack at a sandie.
