"Walt" is British military slang for a "Walter Mitty type" who wants to be in the military or SAS for reasons of personal vanity. Frequently, these Walts never served in any branch of the military or were rejected because of their rich fantasy life.
We have a lot of Walts in the United States. I call them gun nuts. They collect guns because of fantasies they have about being a hero. They don't practice very much, their conditioning is suspect, and when push came to shove, they would probably freeze in their boots. I think "Walt" is a much richer and more descriptive term.
Every once and while, a "good guy" will use a gun to stop a bad guy, but the good guy will not be a Walt or use an AR-15. I cannot find an example of a good guy using an AR-15 or M1A to stop a bad guy; only Walts buy those guns.
Who the hell is Walter Mitty?
Walter Mitty is a fictional character in James Thurber's short story "The Secret Life of Walter Mitty", first published in The New Yorker on March 18, 1939, and in book form in My World and Welcome to It in 1942. Thurber loosely based the character on his friend, Walter Mithoff. It was made into a film in 1947, with a remake starring Ben Stiller scheduled for release in 2013.If you want to save the world using military style weapons, join the Air Force, Army, Marines, or Navy. As long as you can pass the physical, you can be as old as 42 and your killing will be sanctioned by the US government!
Mitty is a meek, mild man with a vivid fantasy life: in a few dozen paragraphs he imagines himself a wartime pilot, an emergency-room surgeon, and a devil-may-care killer. The character's name has come into more general use to refer to an ineffectual dreamer, appearing in several dictionaries. The American Heritage Dictionary defines a Walter Mitty as "an ordinary, often ineffectual person who indulges in fantastic daydreams of personal triumphs". The most famous of Thurber's inept male protagonists, the character is considered "the archetype for dreamy, hapless, Thurber Man".
If you want to be a Walt, go buy an AR and 10,000 rounds of ammo. Grab some tactical camo and a bulletproof vest. You can be a hero in your own mind until you crack and shoot up a movie theatre or a school or your workplace.
I'm thinking we may want to keep high capacity weapons away from the Walts.
