NEFC is called the Never Ending Friendship Circle.
This is where someone announce the start of a NEFC game and gets several people to sign up. She will then place all the names in a jar and then will pick a name out of a jar. The winner will receive a small prize. Then the game will be passed on to the winner and the winner will then have to host the next game and send the next winner a prize and so on.... and so on.
