Bulleh (spelled phonetically) :

Used as slang in hawaiian pigeon. It is used between men primarily, however, plenty women will address a man with this salutation. It stems from the word "bully". In hawaiian pigeon the "U" is sounded/pronounced "ooh" so the word has been slurred from "Bully" too "boo leh".
Often a man will greet another with "Hey boo leh, howzit?" It is like saying "your the bull/ bully, you dah man." It is just a nice way to say "You dah man and I will be submissive to you"
