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."
Person two: "You have to stop fucking her, seriously."

or

Person one: "Old mate dropped by and we watched the cricket for a bit."
Person two: "McGrath had a shocker, hey...."
