"If Bro falls at the end of a sentence, it adds an element of casualness to the feeling. Example - "Give us a hoon on your misus bro." If Bro begins a sentence, then you need to take serious note of what is about to be said. Example - "Bro, does this look infected to you?" If Bro is said on it's own, the tonality defines the meaning: A quick sudden "Bro" means give me your attention ...A long dragged out in a low voice - "Brrrrooooooooo" means "I am not sure I agree with what you are doing" A medium to short "Brrrooo" means "I acknowledge what you are saying or doing" (This can have a "true" at before or after the "Bro" example - "True bro" or "Broooo, true" A "bro" combined with a laugh - "Broooahhohoohoho" can be used as a greeting to someone you haven't seen for a long time. A stern short "Bro" with a serious look means "cut it out" There are many more complicated versions that you will have to learn for yourself."
(Short) Chur bro - Thank you (Medium) Chuur bro - I concur (Long) Chuuur bro - That was awesome/thanks for the beer/feed (means you no longer have any more )
