Often associated with rednecks or hillybillys, this word is actually a mispronunciation. Originally, it was meant to be "brother". However due to accents and slurs, it came out sounding like bubba. This is generally attributed to under-educated, southern caucasions but it's also possible that it is from early african american origin.
"Hey, bubba, you want to go to the store?"

a unique term of endearment orginating from the pakistani word for care taker, babu. which also has roots in strange underbelly of tired under caffinated office workers and 4am friends. all in all an odd evolution of baby which refers to the fact that damn it is good to see you again.
"hey bubba" - god am i glad to see you.
