On the topic of pranks, I want to learn more about the American game known as "chain snatching" which is like capture the flag / king of the hill but instead with gold chains instead of flags and hills.

>In America there is a cultural practice called "chain snatching" which is like capture the flag, except instead of a flag you try to take a chain necklace from other players.
>The winner is the person who holds onto the biggest chain for the longest time
Has any American poster ever participated in this game?
How big is your chain?
