Somebody who collects weapons, usually knives, guns, and swords, and talks a lot about warfare, violence and the the like. Has never actually fought in a war, or been in the military, but loves the two subjects. Fantasizes about being a navy SEAL or a federal agent. Usually a giant pussy when the shit actually hits the fan.
Greg: "Aw man, I wanna be a Navy SEAL soooo bad. Because they have the biggest variety of weapons to choose from. I just bought a shotgun with a pistol grip, so I'm already in training."
Kyle: "I'm gonna punch you in the face you armchair commando."
Greg: "Please don't! What did I do! No, stop! I'm sorry!"
