Gatman is the typical name any high school student takes up in school. To make himself look popular, even thou that person is a total loser and is always trying to get laid. You'll find that person on myspace all day, even in school that person would be using his cell to check his account on it. Gatmen are known to be perverts always trying to get some girl ass.
