A neckbeard is someone who you would not normally associate with. They play Dungeons and Dragons. They bath very sporadically. Fine dining is extra hot sauce on their hot pocket. But do not be so quick to lump them into the same category.
Breed 1: The weeaboo. This is an increasingly common occurence, due to Japans subversive brainwashing campagain of americas youth via television, videogames etc. It is the culture youths turn to when Americas has already been branded into their psyche. Its somewhat alt even. But a healthy interest in Eastern cultures soon turns to madness. An elitest like attitude will appear. "Japanese cartoons are so much deeper than anything America has to offer" " I just like my ramen fresh because it taste better!" "Omg so kawaiiii!!!!" The weeaboo has shed most of his American interests at the cost of fitting in (except with his like-minded flunkies).
Youtubes that Weeaboos will like:
Breed 2: The creepy metal guy.
This type of neckbeard ca usually be found sitting at the lunch table in your schools cafeteria with other fellow neckbeards. He does not fit the nerd mold in a sense that he has super long hair and wears metal band tees or a trenchcoat maybe. This neckbeard most likely plays the guitar or an obscure instrument like this:
The chances that the creepy metal guy type neckbeard plays magic gathering are upwards of 75%.
Breed 3: The GAMER GURL.
A rare specimen, when a female turns to interests usually reserved for the beardiest of necks. Pokemon, D&D, Dwarf Fortress etc. They are often seen as the "perfect woman" to their male neckbeard counterparts, but hardly ever "give it up" and will most likely a) turn out to be bi sexual or a lesbian or b) start dating an attractive foreign boy. While competent in their gaming/ dice rolling/ anime drawing abilities, they will never fully gain the trust of the rest of the clan, due to having a vagina.
