Truth or Dare seems to be used as a plot device in movies much more than it's actually played in real life. In the game, a contestant is asked a question and must choose between answering truthfully or performing a task to be named by the questioner; both choices are often designed to play on the contestant's sexual insecurities. Tension is created as the contestant must decide whether performing the as yet unknown task will be more distressing than exposing his or her personal secrets. The characters in this film appear to be unfamiliar with the rules, as contestants are ordered to choose between truth or dare before the question is asked, thereby rendering the decision arbitrary and pointless.
