Heads or tails refers to the two sides of a coin. When a decision must be made with two equally viable answers, or two people disagree and must find an equitable way to choose between two answers, a coin may be flipped. As one person tosses the coin in the air, the other person calls either heads or tails. Heads refers to the side of the coin with a person’s head on it. Tails refers to the opposite side, not because there is a tail on it, but because it is the opposite of heads.
