In mathematics, a limit point of a set S in a topological space X is a point x that can be approximated by points of S in the sense that every neighbourhood of x with respect to the topology on X also contains a point of S other than x itself. Note that x does not have to be an element of S. This concept profitably generalizes the notion of a limit and is the underpinning of concepts such as closed set and topological closure. Indeed, a set is closed if and only if it contains all of its limit points, and the topological closure operation can be thought of as an operation that enriches a set by adding its limit points.

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.

In actuality, its simply slightly less understood then more generic forms of greeting (such as mate).

Cobber: the UK/Australian Bud-destroyer. The Irish-Americanism Bud is occasionally used as a slight or put-down to terminate a conversation, by enunciating it with a sharp emphasis, thereby imputing an impersonal distancing, paradoxically coupled with a sneering overfamiliarity. In the former English colonies, a [riposte] to this shorthand New World affront has been found in the resurrection of an obsolete colonial appellation of fraternal affection: Cobber, or just plain Cob. It is effective as a Bud-destroyer because its usage is so unexpected, completely shattering the false familiarity of Bud, at the same time providing [social proof] that you are indeed big enough to meet casual man-to-man disparagement head-on, and deflect it straight back [like water off a ducks back].
