Facebook Guilt: An attempt to support or bring attention to a cause by posting a guilt-inducing status update along the lines of "If you believe/don't believe in ___________, repost for the next _______ minutes/hours/days;" the implication being that if you don't repost you are taking a stand AGAINST said cause.
An example of Facebook Guilt: I care about America’s soldiers – IF YOU CARE TOO YOU MUST REPOST THIS!!

Defensive reaction to finding out someone is not on Facebook. Usually indicated by the word "just". As in, "I just use it to stay in touch with friends/family".
If I happen to mention that I'm not on Facebook, nine times out of ten someone's Facebook Guilt kicks in, even though I have made no judgement whatsoever.
