To “fanny” the opposition is to win a game without the opposing team scoring any points – i.e. 13-0.
To be “fannied” is to lose a game without scoring any points – i.e. 0-13.
The origins of the term are a mystery, but in France when a player loses 13 to 0, they are said to fanny and must kiss the bottom of a girl named Fanny. In France you will often find a picture, woodcarving, or pottery figure of a bare-bottomed girl named Fanny.
FPC have their very own Fanny for this purpose – generously donated by Martin and Nicole at the 2015 AGM. In some competitions a novelty prize is awarded for “first fanny”.
