That's some neckbeard vomit right there. Nice.
I investigated and discovered that neckbeard, unsurprisingly, means
Facial hair that does not exist on the face, but instead on the neck. Almost never well groomed.
OK, but what is neckbeard vomit? Google only returns four hits for the phrase and one of them is the comment in question. To make matters worse, the poster of the comment seems to consider it a compliment, while to me it seems very much the opposite.
So, what is neckbeard vomit? Is this a geek slang term I have not come across or was it coined by the comment's author?
