Geoff Fitzpatrick

From Frikipedia

A variant of the Geoff O'Clock system used to specify a Geoff of the utmost high order.

Instead of saying "Geoff's in his office at...", the phrase "Geoff Fitzpatrick is in his office at..." is used. This subtle but crucial change in phrasing is used only sparingly but indicates a whole new level of Geoff.
