A card that is used throughout a tight group of friends that is given to someone in the cardholders time of need. A somewhat "favor" card that is given to someone so that they help you out. Once given away, the only way to gain it back, is to do a favor for the friend.
In the movie "Good Luck Chuck" Dane Cook uses his friendship card to get his friend to date the fat/gross/ugly girl by the pool to see if she would marry him.
