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.
