I admit I am a horrid person, not picking these things up and living in South Carolina myself, but I know I miss things or just don’t realize that they aren’t called that elsewhere because it’s normal to me. Also my speech patterns, typically, reflect a more northern choice words because of my parents and their own so perhaps that either explains it or makes me that much more oblivious.
Examples that have noticed for my general area:
Outdoor house hook up thing = Spigot
Cart (Shopping cart) = Buggy
Hose = Hosepipe
Bucket of water = Pail
Pop/coke = Soda
