Well....on the set of the films, the hobbits (spec. Billy Boyd and Dominic Monaghan) invented a fake poking-game which included a series of "tags," "tigs" and "togs." This thread (and its predecessors) were named in honour of the fake game. The full story can be heard/seen in the behind-the-scenes of The Fellowship Of The Ring: Extended Edition. 😉
