The reaction from the audience we suspect the author intended. We can't really know whether it was intended. It may have been, or it may have been that the author was aiming for something completely different and just missed. We can occasionally get a quote in an interview confirming, or at least claiming, that a specific audience reaction was intended, but usually this term is only useful for fans talking to fans. Only give examples of this trope as Trivia under Word Of God.
