are you serious? Not only is it shallow, it's abusive. Why are you condoning abuse? His girlfriend should encourage him and build him up, not tear him down. There is no reason for someone to make comments like that in front of people when she knows it bothers him. He should only develop his legs because it's what he wants to do, not because his girlfriend humiliates him into doing it.
His screen name is from 2010. He has been insecure about his legs for a minute.
