I think coming up with your own names might not be a good idea. For example, the figure you mentioned above would likely be called as "a shark tooth with 1/2 roll up and 1 positive snap down." (You would probably also hear "Pull to an upline. Half roll. Push to a 45 downline. Postive snap." while you flew the figure.) If you were use to hearing "bottom tooth, 1/2 roll, snap" you might get confused. Also you would likely confuse someone you were calling for.

Have you thought about starting in basic? You can always move up, but you can't move down.
