Truth or Dare is a classic game usually played with friends or family where one person asks another person to choose between answering a question truthfully or completing a dare. The person can choose whether to answer the question truthfully or to complete the dare, and then the person who asked the question or gave the dare sets the next challenge for someone else to choose between truth or dare. It can be a fun way to get to know each other better and to have some lighthearted fun.
