He's a jacka$$ when wants to be
It's all about Leo to Leo. So he is that Jock at school at all the girls want until they get to meet him and begin to resent him, not the cheerleaders. He thinks he is better than everyone until he gets a wake up call.
He always has his gym bag just in case he has time to go to the gym and he always has his cell phone with girls' numbers in it.
When Leo was little everyone loved him and treated him like a god. Then he grew up and was forced to be nice. He really didn't want to so in high school, he went crazy and back to his old ways of being a jerk/jock. Maybe the Giants will straighten that out of him.
