Okay,It's a game,That i found out in some Israeli Forums,
It works like that,
In every post you have to write a number, in an order (1,2,3,4,5,6.)
(No Double POSTs)
Every time you get to the number 7 you have to say Boom.
7 BOOM.7,and it's doubles (14,21,28,25 and Etc.)
If you forget to say "BOOM" Everyone have to start from the beginning
