1. One who frequents a gunshop and tells lots of "no shit, there I was..." stories.
2. One who buys lots of military style weapons at the gunshop and has no real reason for an M-4 or AK-47 except to play dress up in their house with props.
3. One who thinks that buying a rifle that the military uses will make him look tougher.
See that guy over there dressed up like Rambo? He's the local gunshop commando around here.
