Neckbeard isn't you, Tigerstripe, from what I remember. Beard on neck (and face) =/= neckbeard.
The neckbeard thing is a younger (white) punk's signature, at least around here. Think full beard - now shave your face. Not the chin or neck - just the forward part of the face, mustache and sideburns. Looks ridiculous (sorry if I offend someone here with a neckbeard, but as a fellow bearded dude, it really does). I'd say google it but you'd live better if you don't
It does seem like a lot of the 20-ish manboys who would like to be badasses but can't be bothered to actually do something and/or ICP "extreme fans" seem attracted to the style.
What that translates to in gunshopland is guys who know a modicum about guns and therefore think they are badass experts ...and are willing to work for minimal wages, since they mostly are retail staff, on the counter sometimes. I know I've met my fair share of guys who, since I'm standard generic white chubby guy, think they *must* know more than I do about guns. No way can I be "operator level". Not that I know everything, but I have a habit of asking retail people questions to which I already know the answer, to see what kind of BS they are intending to spew, and my inclination to support their business varies accordingly.
Oh, and I think the next neckbeard that suggests my wife look at the 'pink guns' is going to get a Carolina-girl whooping. Good thing I know some lawyers, cause they're sure to sue once they get out of the ICU.
