Texican

A “Texican” was (pre-1836) a person from Texas (then part of Mexico) of non-Mexican ancestry. After Texas became independent and then a state (post-1836), the term “Texican” began to be used for a person of Mexican ancestry living in Texas. Exactly the opposite!

Oklahomans use the term “Texican” to demean all Texans (as being of lowly Mexican ancestry).
 
In the 1966 movie The Texican, the term meant a Texan (an American citizen from Texas, of non-Mexican ancestry) living in Mexico—somewhat similar to the pre-1836 use.
 
In the 1970s, “Texican” began to be used for “part Texan and part Mexican,” similar to the term “Tex-Mex.”

For the record, I wrote “Oklahomo” and “shithole” because this is smack central. Just like the ol’ texass or texican thing you guys do.
