Lets see we have:
Tacticool - someone who effectively doubles the weight of their weapon with useless items.
Mall ninja - 20 something "bad ass" security guard who couldn't pass the tests/requirements to be a real cop, so loads up on everything he sees in the movies, and talks down to people, usually still lives with his parents.
Bubba'd guns - I took shop in high school, I can fix this!
Internet commando - usually a 12-17 year old kid who claims he's the best shooter on the face of the planet and owns 100 guns when he really couldn't hit the broad side of a barn, and has never shot anything besides in counterstrike. The Internet commando usually "locks up" when confronted with anything "IRL", and proceeds to curl into a ball and weep while rocking gently back and forth.
