Someone who lives to get free t-shirts from conferences, conventions or other social gatherings

I picked up so many free t-shirts at the Consumer Electronic Show I felt like a t-shirt whore.

t-shirt fan

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.

1.The author of definition number 2 is a T-shirt fan.

2. The majority of University of Texas fans are T-shirt fans.

T-shirt fan

Anyone who claims they are a "fan" of a particular sports team, even though they had no prior support for/interest in the team until that team started winning. These types of fans usually wear t-shirts supporting a particular pro/college sports team even though they do not live in that city or did not go to that college. Plenty of these fans did not even go to college, and some are lucky to have past a 6th grade education.

After UT won the National Football Championship, many illegal immigrants from Mexico became a t-shirt fan.

T-Shirt Willy 

When you put a pair of pants on in a hurry over a shirt which is then tucked into the pants. Sometimes the bottom corner of the shirt sticks through your fly, which is called a T-shirt willy.

*in PE changing rooms after the lesson*

"no i dont"
"yes you do look"
".......shit"
