Hutch, sideboard, buffet? To me it's a sideboard.
Country fried steak or Chicken Fried steak is the same except in TX where it's always called chicken fried. (I guess as opposed to catfish fried. Or okra fried. Or maybe even French fried.)
Sack, poke, bag, satchel? My ex always toted stuff in a poke, but I usually carried it in a bag.
Then again, in some parts of TX, they "carry mama to the doctor/church/store/Aunt Jean's"...doesn't matter if she weighs 300 lbs or not, they "carry" her! (OWw!)
Soda, pop, drink, cola to me is nearly always a regular Coke, with ice, in a glass, or "go cup" from a fountain/drive-in.
Movie, film, flick, theater? Movie here. "Theater" is for live performances.
Frigidaire, ice box, frige, refrigerator, cooler? I mostly say 'frige'.
Whole-house-fan vs swamp cooler? First heard the evaporative cooler in my daughter's newly-built house called "swamp cooler" when I visited her in El Paso in June. As it was 100 degrees with no shade, and there was not a single swamp for hundreds of miles around, I just did not get it!! They put in AC within the year, LOL!
