From BRWiki

A stub is a placeholder indicator or marker for an unfinished article in a wiki.

Its purpose is to inform visitors that they've arrived at a very unfinished page (as opposed to a normal wiki page which simply never gets finished), and also to automatically classify the page to make it easier for contributors to find and fill out.
