retail alumni

A fan of a college or university's sports team only because they bought or own a shirt from it but never graduated from it.
Their exclusive association is through being a fan of the college or university's sports team.
Often the fan is too stupid to graduate college but can regurgitate great volumes of team fact, history and legend.

Steve is a retail alumni for Alabama only because his inbred uncle-daddy and cousins are also a retail alumni.
None of them have even set foot on campus, let alone attended, and probably couldn't even show you where it was on a map.
