Having recently moved to the South (from IL to TN), I have definitely noticed some differences between southern vocabulary and northern vocabulary. Here are a few of the words and phrases that I have heard that are definitely southern.
buggy (n.) – shopping cart
Knoxvull (n.) – Knoxville; note: any city name ending in -ville is pronounced as -vull
Krystal (n.) – an alternative to White Castle with equally greasy and questionable food
fixin’ to (v.) – getting ready to, preparing for, about to; example: “He is fixin’ to go to the store.” (more…)
