First of all, as was once documented on the greater University of Virginia article, you are described by pep band members as a Google "stuffer"... creating a bunch of websites about the Pep Band and even trying to get searches for "UVa Marching Band" and such to go to your own "websites".  A more reliable source would be Cavalier Daily articles from the 1960's.  As you could guess, when my father attended the university from 1961-1966, and fear of State U-ism was all around, they didn't make webpages.  But if you look back at those student periodicals from the 1960s and up to a decade earlier, you'll see the term was widey used to refer to the large (more than a few thousand students as UVa had at the time) co-educational universities.  The bru-ha-ha about State-Uism came to a head when women were admitted in 1970... I had to read through all that stuff in the late 1990s for the "History of UVa" class that I think is still taught at the university.  You're still at the U., check out the old collections of student periodicals, yearbooks, whatever you can find... you'll get a sense for the history of the term. –
