I happened to think of some phrases I say on a daily basis, that would sound really foreign to many ears. I have to watch myself when typing here, because you may not get it. Here are some Texas-isms or whatever you want to call it that I generally say daily.
Yall- you all, everyone, everybody
Tear it up or tore it up- several meanings. It can pertain to food, "Mmm, I could tear some watermelon UP right now!" or "She tore out to the store." (going somewhere in hurry) "Hmmm, I better not eat that, I don't want to tear my stomach up." (don't want digestive problems)
Wore down or Wearing me down- really tired, exhausted, mentally stressed..."These kids are wearing me down." (emphasis on do-o-w-w-n) "Man, I am wore down from shopping."
Be back directly- I'll be back soon- "I'm going to town, be back directly."
I reckon- I agree
"Lit a shuck." or "Lit out"- went somewhere fast- "He lit a shuck to the outhouse." or "When she saw the coyote she lit out." Related to 'high-tailing it", as in, he high tailed it to the house.
Fixin' to- about to, going to..."I'm fixin-a cook dinner."
I can't think of anything else now...if I do I'll add to the list.
