A Fake Smile

AKA: Pan Am smile or Botox smile.

To deliver withering insults with a faux sweet smile. It's a socialized way for high ranking classy women/men who have to refrain from stooping to their haters level when in reality, they're desperately wishing that the person would be decapitated by a flying toilet carrying their own trots and any bullshit that the looseness of their bowels cannot carry.

A fake smile can also be used to replace the middle finger or a punch to the mouth to those who don't seem to understand that you could not care less of what they think of you. Their jealousy is a good indication that you must be an awesome person of the highest calibre to spark such fury, envy and outrage.
