Eli5: What's the behind the meaning of a "neckbeard"?

Can someone please explain what a neckbeard is? Why do they wear fedoras? Why the "le" in front of words? Is it an insult? I'm still pretty new to this and a bit lost?

A decent beard should be, to at least some degree sculpted or manicured. Just basic hygiene really. 

A "Neckbeard" refers to someone who has a beard not because they want one, but most likely simply as a result of inattention to grooming. Usually paired with wrinkled, smelly clothes, a surly attitude, and poor social skills.
