He is an individual who will never say no, and it turns on them in the long run. Usually really bad at math. But is a very good looking person, and most girls want to be with him. They waste a lot of time being with people they shouldn't be with. They are intelligent, but say very stupid things and come off as stupid. Usually a very touchy person if with someone, and a very loyal individual.
Look at that guy! He can't even do basic math! What a Joe.
He must be a Joe because he is so good looking!
A person who is so insecure that he would beet up his younger brother over a space on a bed. Joe is so fat that he has to have showers in the Atlantic. His nickname is fat humms
Joe is someone who only has friends because they pity him. Everyone knows he lives a sad and talentless life so people tend to take him under their wing. An example of this is when teachers give him good marks in P. E because they think that will make him feel less depressed. Joe in German also stands for "shit-at-stoolball"
All in all, give Joe pity because he really has no talent at all.
