1) a beard that has been allowed to grow down onto a portion of the neck, hence the phrase 'neckbeard'

2) a creepy/pedophillic excuse of a man with a neckbeard (see above). Is stereo-typically attracted to underage anime/hentai girls, and will fall head first into love at the sight of a single 'uwu'. It is advised that you stay as far away as possible or they might hit you over the head with a katana /j. You can identify one by their love of the phrase "M'lady," and the shitty fedora that seems to be permanently attached to their head. Usually overweight but you never know these days.

A noun not referring to a beard that grows down to one's neck, but to a self secluded troglodyte, often represented as a weeb or a person who isolates themselves to the indoors and typically is obsessed with pop culture. Many neckbeards lack hygiene and social cues as well as being typically a self proclaimed "gentleman" or, to the rest of society's terms of phrase, a simp.
