look up any word, like the eiffel tower:
V. To obsessively collect and hoard some nerdy pursuit to the point of excess and often at the expense of others. Derived from the noun forms of "neckbeard" (both definitions).
I went to the store to get my kid the new action figures from the latest comic book film, but they were sold out already. I later heard one guy neckbearded them all in one purchase.
