The school where my son teaches has a "nutty" school mascot. To me it appears to be a locknut, not a split locknut but the kind that has a bunch of rectangles coming out from the central circle. The mascot could be that or it could be some kind of gear. Anyway, he insists that this hardware is called a "vok" and I think it is called a vok because it is the mascot of a vocational (voKational) school.
In general I am against having hardware as mascots but is there such a thing as a "VOK".
