A bogey is what you get when you complete a hole in one more
stroke than what is par for that hole. Par is the number of strokes
you are supposed to take on a given hole and there are par 3's,4's,
and 5's on a Golf course
A birdie - a bogey is one shot over par on a given hole, and a
birdie is one shot under par on a given hole - so, a bogey is two
shots worse than a birdie.
