A noticeable growth of hair on a persons neckal region. Usually the face is well groomed but they decide not to groom the neckal area. No one knows why for sure but professionals have speculated that it might be afraid that they are afraid of cutting their neck over childhood scarring. The hair that grows on the neck is also referred to neck pubes.

Something a person does while sitting in a corner dive bar, probably leaning on an old Jukebox playing indie music or a hipster easel made of repurposed burlap, while watching well-groomed men attempting to pick up opulent females. The action requires a lean just enough to offset one's balance while simultaneously billowing out the stomach for what appears to be the preparation of a boisterous laugh, but instead ends in a silent chuckling motion with a horizontally-facing fist to the mouth.
I went to the corner dive trying to snag some local talent, but some well-composed douche in the corner threw me off with his super distracting neckbeard chuckle.
