West Texan here too, just not as far west as Midland. Here is a funny story. True Story:
A local farmer I knew had a farm hand from Mexico. Every day the farmer took the farm hand home and as he got out the farm hand would always say “besi mi culo”. The farmer would smile and say thanks and went away believing the hand was being nice. The hand smiled bigger. Years later the farmer found out what “besi mi culo” meant. By then he could laugh out loud. I can tell you what it means but you can also look in the urban dictionary. Let me know if you want me to say.
Can’t we all just get along?
LOL
Besa Mi Culo
