The freakin Okies...
Stupid mascot(only an Okie would worship a wagon).
There's a ton of OU transplants in Dallas and they are some annoying sumbitches heh

and they all seem to drive giant Chevy SUVs...never Dodge or Ford...always Chevy...
And they invade my home town once a year cause gridlock on the highways and stink up downtown(just kidding kind of)
And of course they have beaten the Horn's butts the last few years unmercifully and they have won the national championship I so badly want.(none of my favorite teams have ever won a champsionship since I've been alive...ugh...)
Texas A&M...
hate their traditions and cult like behavior.(My sister and her husband are both Aggies and I've seen the nonsense first hand. Almost got into a fight with some yahoo that tried to knock my hat of my head when I was in their student center).
They are overly obsessed with Texas and everything they do is centered around this burning drive to try to prove they aren't inferior to UT. I mean seriously what kind of school has their fight song be nothing positive about their school but rather a lengthy insult song about their in state rivals?
Their stupid fans that despite getting their butts handed to them all the freakin time still think their school is the best football school in the state.
Arkansas...bunch of hillbilly turds that left the Southwest conference and in general show no respect to the people they play.
Miami...I just can't stand them most of the players from the NFL I hate played at Miami.
