Old Mate is a brilliant Australian invention used to refer to someone that you are somehow connected with but don't personally know. Its general tone is derogatory but its not offensive.
EG: if you saw a drunk person stumbling across the road you could say..."have a look at old mate over there" or in a traffic incident....."and old mate just drove straight into me"

n. Australian colloquialism. A replacement term for a person's name within a sentence. Usage stems from the idea that a person need not be named during a statement or anecdote, but that his or her identity can be deduced by the context of the message.

Sometimes the identity of old mate may not be discernable from the message's context. Quite often in such instances the identity is immaterial to the underlying message.
Person one: "I had sex with old mate. Again."
