RAFO is a term Brandon Sanderson uses at signings as a non-answer for prying 17th Sharders. It means "Read and Find Out." When Brandon uses this, it is neutral, and neither means one is right or one is wrong. Many things are RAFO'd because they would spoil future books.
Robert Jordan popularized this term in this genre, and Brandon "inherited" it, so to speak. Brandon feels bad for simply stating "No, I won't answer.", so he has the RAFO cards made physically. Instead of saying it, he hand out the cards to the fans. It has become a trophy hunt for the fans.
RAFO can also be used as a response to questions that are meant to be discussed by fans or ones that will never be answered.
