Facebook words
Facebook has introduced a lot of new social mores and situations, and I think many of them stand to be defined. Example given: —Ashurbanipal 00:52, June 28, 2011 (UTC)
 * What is the word for the scenario where you neither accept someone's Facebook friend request nor ignore it? Is there a noun or adjective for that person who has been put in friend request limbo? Is there a noun for that limbo? Is there a noun for the confused feeling you get when you're torn between not really knowing a person well enough to add them and also feeling obligated to add them?
 * What is the word for the older relative who doesn't understand how Facebook works? for the overly-personal wall post they make that should have been a message, or vice versa?
 * What is the word for a person who immediately adds everyone they meet as a friend on Facebook, without discretion?
 * What is the word for a person who posts a picture of their baby or pet as their own profile picture?
 * What is the word for the person who asks you why you unfriended them?
