look up any word, like bae:
someone who stays up late using/checking facebook very late at night, like 2 AM or so.
-dood, that creeper is a facebook vampire, stayin up this late.

-"Ahh, facebook vampires always up this late at night." you see them in chats.

-This facebook vampire needs to quilt stalkin people, posting weird shit on facebook, posting weird status/photos of themselves/videos. and posting useless shit, and spamming.
