It's a golf term meaning that one has gotten a ball in the cup in one shot from the tee off. It has been slanged down to many references of getting items into different holes on the first try. Some of which are sexual in nature.
A hole in one is when you hit the golfball from the starting position into the hole with one hit. So say you just finshed a hole and you going to your next, Well now your about to hit the ball and you give it a good whack then you hear the ball you just hit make it into the hole. That is a hole in one.
