I chanted "SECSECSEC" mockingly at Arkansas as they lost their final game in Austin, after they announced their plan to leave the SWC for the SEC back in '90.
I can't imagine I'd ever chant it again, but if Texas manages to beat OkState and win the B12 championship on Saturday, I'm sure there will be some surly Longhorn fans in JerryWorld, chanting it in an effort to mock dickface Yormarck for his clear anti-Texas bias.
