These "labels" are kind of amusing, to me. We have two programs with an additional "A", UGA and UVA. Maybe there are more. Florida is just UF of course. South Carolina is an outlier, but I term them USCe. UNC works, the various "XSU" programs are clear. If I talk about "UI" folks don't seem to worry if I mean Illinois or Indiana.
BC is kind of fun, it's not really a "college" as we speak about them. Georgia Tech is clearly GT, not GIT like MIT. It really should be GIT. If I say "VU", it's not "Vanderbilt University. A&M is a fun one, we used to have a ton of "A&M" schools about, and still have a few, some are HBCUs.
We've got Northeastern Oklahoma A&M College, in Miami, hometown of Steve Owens. It's a 2-year institution. Probably originated as a 2-year sports factory for academically unprepared/challenged athletes to get their grades up before proceeding on to 4-year schools. The teams are called the Norsemen. I suppose that makes sense on some level, somewhere.
"OU" makes no sense outside the context of the old Big 6/7/8, where all the "U of X" schools were called "XU." Nebraska shifted to "UNL" when it moved to the B1G. But, really, "NU" was not what I heard other Big 8 fans call them, compared to "KU," "MU," and "CU." They were either "Nebraska" or "Huskers."
Maybe just because "everybody else around here does it that way," the (private) University of Tulsa has long gone by "TU."
Oregon is "UO," while Ohio University is "OU." No question about Utah--it's "UU."
Arizona is "U of A"--not "UA." And not "AU," which is Auburn, of course.
I can remember when I at least thought that Virginia Polytechnic Institute was "VPI."
There used to be an "IUPUI"--pronounced "Ooey-Pooey," I think. Indiana University-Purdue University in Indianapolis." Which reminds me that Indiana is "Indiana University"--"IU."
Aren't Alabama and Arkansas both "UA"?
