So can someone help explain what's the deal with calling people neckbeards as a mean to insult them? I mean, I've seen this term used a lot (sadly way too often against the brony community), and I'd just like to get a sense of what the fuck's the deal with it. I've read a few definitions online of the term, but I'd like some input from you guys.
Edit: Oops. I totally meant to place this in "Society and History." I'm a fucking moron.
