RE: Hunting slang?
As others have written there are numerous names for those who buy all of the best equipment and don't know how to use it. The one my buddies and I use is "Bass Pro Mannequin" We use the term "Mo Mo" for big deer and large fish. "Boone and Cricket" for small bucks. When we rib each other for buying a model of gun or bow that we don't think is the best we call it a "Boat Oar". Those are just a few off the top of my head.
