Crying Uncle

What does it mean to "cry uncle" to you?  Well, I looked it up online to see the origins and meaning and it isn't a playful little thing.  Although we many times as children may have played that little game, it started as something much more like bullying.  Think about how you deal with this and how you would feel if you were in this situation.  You may be, or you may know someone who is on the receiving end of bullying. After you listen, let me have our feedback.
