Bo

An American English slang term used in the South, in both general and endearing contexts. The word's roots and primary usage are found in Southeastern North Carolina, in mostly rural areas and smaller towns, but can be heard throughout "Tobacco Road," as well as parts of South Carolina. Perhaps stemming from the term "buddy" by slurring the latter half of the word, but also less possibly a play on the term "bro." Not to be confused with the French term "beau."
