Australian colloquialism meaning "mate" or "friend", but not necessarily in the literal term. Can be used to address a stranger in leiu of "Hey, you there!" or "Hey, kid!" in a more friendly manner. As the word's been used since the earliest Colonial settlements of Australia, many Aussies mistakenly believe the word is archaic and no-longer used. In actuality, it's simply slightly less understood then more generic forms of greeting (such as "mate").
