Many sports related activities utilize the term, "rat", to describe extra devoted or obsessive enthusiasts. Examples are: Gym Rat for basketball, Diamond Rat for baseball, River Rat for those into the boating and waterskiing scene, and Desert Rat for the many who frequent the deserts to camp, ride atv's or race trucks. In that vein, why not something like "Rifle Rat" or "Gun Rat" to describe the truly looney amongst us?
