When someone updates their status on facebook with cryptic messages so that others will comment. Usually because they're an attention whore.
"OMG, I can't believe that just happened" would be Half Post of "OMG, I can't believe I really don't have anything important to say, so I'm going to pretend something dramatic is happening to me, so people will pay attention to me and I will feel loved."

whereas your supposed to respond "Are you alright?" (As if you really care, and the only reason you are really asking, is because you feel sorry for them.)

As mention on Keith and the Girl.
