A socially inappropriate action performed within a social network . Often used as a passive verb, to be faceplussed, to describe being the victim of a socially inappropriate action. For examples, sharing a private photo with all of your friends instead of just one. It comes from a combination of Facebook, Google Plus, and the facepalm you perform once you realize you did it.
This guy totally faceplussed me yesterday by posting a political rant on my feed. Now all my friends think I am some kind of doomsday prepper.
