Dover (coll.n.): The residual list of people on your Gtalk roster, whom you will never ever ping in your life, whose status messages are never anything to be amused by. They still subsist there because you ‘might’ need to ping them ’sometime’. (The physical world equivalent of a Dover is an Outram, which is any trinket that you put aside for later because it ‘might’ be useful. It serves the singular purpose of surreptitiously bloating up the attic / storeroom / garage).
