Half Post 

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.

half of the people who posted definitions on this website 

are retarted hypocrites and faggots who believe everything they see on the fucking idiot box. particularly the ones who posted definitions of certain people. most of the definitions r not funny, and in some cases half of the definitions are all the same. specifically, the definition g-unit. g-unit kicks ass, but 75% of the definitions said g-unit stands 4 gay unit. That joke was not funny. Whoever thought of that joke should be proud of himself, he got 80% of america to copy him and still have no idea who he is. i used 2 be a member of this website, this is the last definition im posting.

half of the people who posted definitions on this website: im cool, i have a computer, i believe everything i hear from CNN to the national enquirer, im not funny.
