This is a fun activity. Something that must be experienced at least once. It doesn't sound like a very nice game.
If you've never experienced it before, here's how it goes (one example anyway):
Start by identifying a serious problem. Then blame someone.
Point a finger directly at someone unrelated to the problem
Come up with some unfounded false accusation to apply, clearly implicating the other person
State it loudly and unashamedly
Watch that person shrivel in terror
The goal is to keep the BlameSession? going as long as possible.
Remember, at no point in time is anyone allowed to offer a serious remedy of the actual problem.
Bonus points for blaming people not involved in the meeting but keeping the BlameSession? alive.
The only way to end a BlameGame occurs when it seems inevitable that the BlameSession? cannot continue. At this point, election of a ScapeGoat should occur.
