Wearing Daddy's Shirt

This picture is quite literal I think.  He is a kid wearing his dad's dress shirt that is a couple sizes too big and he is drinking Gatorade for the electrolytes so that he can party till midnight.  Wear a shirt that fits, idiot.

Even if his drink is actually a friend's toxic Gatorade cocktail - the staple of any freshman's lame dorm room life - he is still pretty pathetic.
