I have heard the term "Mall Ninja" several times and wonder were it comes from? I believe that it is used to refer to the 18-25 yr old guy who claims to be ex-special forces, CIA or whatever. Whose sole source of knowledge on subject is one article they read in SWAT or another magizine.
An example would be the guy who shows up at the public range with a laser pointer superglued to his Glock. He also has an SKS with an EverReady flashlight ducted taped (with black tape of course) to the baynoet.
Do you have a better definition or example? Am I close?
