In the game of necking or gilling, which is slapping someone on the back of the neck and scratching their neck when they say something stupid, if they say something amazingly stupid that is heard by many people, someone yells "FAMILY PACT!" and everyone gets their turn of giving them a neck
My gosh! Name-o has gotten like 30 family pacts!
