The fear any OU Sooner fan has for anyone from Texas. If you say you are from Texas, they assume you are a Texas Longhorn fan in Oklahoma with the intent of saying or doing evil to an OU Sooner fan. If you say Texas, they will automatically add Longhorn with a Pavlov's Dog type of reaction.
Hey, Joe, don't be such a xenophobe toward this Texan. This Texan is a Texas A&M Aggie fan, and they brand Bevo Longhorns if given the chance, with 11-0.
