Ughh, I can't stop looking at that picture. I think it's because it makes me feel better about me. Also there was a guy at my highschool that looks exactly like that. All through school he would say how we were all stupid, and couldn't match his 168IQ and that he would be the next big internet phenom; I saw him working at a gas station recently.
If that is the best example of neckbeard, then I know totally understand the insult.
I also assume everyone on the internet looks like that, until I know better.
