When a comment is uttered that attempts to be witty, intelligent or poignant but falls flat, i.e. a bad joke or stupid observation/suggestion, a neckbone must be given to the perpetrator. This involves yelling out "neckbone!" and grabbing the back of the person's neck with the palm of the hand and pulling across in a swift, hard motion...if done properly, it will leave a red mark, similar to an Indian burn.
Person 1:"Seriously, Jessica Simpson is really talented, you guys."
Everyone Else: "NECKBONE!!!"
