Janet:
He's definitely nice, but his fedora and pony collection lead me to believe he may be a neckbeard.

Should I be concerned?

Brad: Oh, not really. He's harmless, but he might cry and make you feel guilty when you won't touch him.

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.
"This neckbeard would give me mod until i said uwu,"
"What a fucking creep,"
