If you know that reference, you are a Louisville Cardinal basketball fan of some longevity.
If not, it denotes you're a relative newcomer. (Which doesn't mean you are not as fiercely loyal as some of us old farts, just that you haven't been at it as long.)
It hearkens back to the halcyon days of U of L hoops. The incident I reference came about sometime in the late 70s or early 80s. When the seats of Freedom Hall up close and far away were filled with true Cardinal fans, not corporate guests.
