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.
