A Dub? Well are you picked last at dodgeball every time? Do they also call you a "chucker" in basketball? Do you always get put in right field during baseball / softball games? When you are at bat do they hollar "Can't hit, automatic out" and they are right? If traded are you the "player to be named later"?
If so, my poor friend you are a dub.
But it's okay you might be great at soccer! And everyone is a winner in soccer!
