For the uninitiated (or Amish) among you, a selfie involves taking a photograph for oneself, not necessarily but most likely to get public adulation. The shots generally feature pouty duck lips, a state of partial undress or even complete nudity. (Bonus points if it's a mirror-pic with some lens flare.)
