Eating Bread At Basketball

So, I play basketball with some teachers a few times a week. Before coming to Taiwan I haven't played basketball since gym class in high school. I have a good eye for the open man and I'm okay on the boards, but my shot needs some work. I also need to work on dribbling and driving to the net. Well, after several weeks I can say that I am improving a lot. I have a really good hook shot, but sometimes my shot still falls short. Yesterday, after making a sweet one-handed hook, I missed the rim twice in a row. A teacher said, "Oh, you are eating bread." I looked puzzled until another teacher explained, "You shoot an air ball."
