The University of Oklahoma is well known for its football team. This team usually dong-slaps it's in-state rivals, the Oklahoma State Cowboys (who also go by "Pokes" or even "Jokes"), and have very competitive meetings (which they usually win) with the Texas Donghorns and the Nebraska Cornhuskers. The Sooners are easily in contention for college football's national title every year. This, as you can expect, generally translates into an almost cult following by their fan base who use religious terms such as "Patriarch" for coaches and former players and "Saint" for current stars.
The University of Oklahoma's football team is easily the 2nd greatest college football program of all time.
A big 12 college located in Norman, Oklahoma. OU is mostly known for its football team, which usually does very well. Lesser known to the public outside Oklahoma is the fact that OU boasts more douche bags per capita than any other school in the continental U.S. It should be noted that a direct result of this douchification is the fact that the university of Oklahoma is OU, instead of UO. And, their mascot is a wagon, which is useful because they need something to carry all of their bandwagon fans who didn't graduate highschool...
All of the janitors at my school are University of Oklahoma fans.
