A fan of a College they would never be accepted to. Often get very defensive of said team, and respond with statements that don't really make a lot of sense. IE-Using Mike Sherman in a Tech rant. A true UT fan would know that he is aTm's coach, and TT has no afilliation with him whatsoever.
Sometimes make themselves feel better by saying that everyone is a T-shirt fan because they dont play for their schools, when in reality, if a person is attending, or has attended said univeristy they have put money into it. This allows them to cheer all they want.
