When friends post things to friend's walls and then delete them hoping to catch it before pissing them off, not realizing that most people with smart phones got the message before it even hit facebook.
facepost regret post something to your wall like : "Get off your soapbox!!" (meaning, I didn't vote the same as you in the last election)
