Chinese whispers

Chinese whispers is a game that people play when they are in a group. In the game, one person will whisper a phrase or sentence to another person. That person will then pass it on to the next person, who will do the same thing until it has gone all the way around the group. Usually each person will change the phrase or sentence a little bit, so by the time it gets back to the first person it sounds different.
