Signature Moves for a Quarterstaff?

So I want to build a Gnome Quaterstaff master. But I am at a loss for what to use for the “Signature Move” provided by the Grand Master path. Some of the shield trick look good. But I don’t know that using a shield trick with a quaterstaff is fitting. But, then again, if I care about fitting a Signature Move to a weapon, most of the tricks that are not based on shields assume either piercing or slashing damage in the flavor text. Which makes less sense than on of the blunt effects of a shield. Any Ideas?

If there are no weapon tricks that work with a Quarterstaff that are not already on the Quarterstaff trick list, then is there another path that could be used to enhance a Martial Gnome Quarterstaff master? Or, should I plan on skipping a path?

The concept is currently a Corpulant Gnome defender of the Gnome City of Milandir that lost his land and who drinks a lot. Think Little John of Robin Hood fame. I will entertain anything that meets either the quarterstaff or little john concept.
