It's really simple

An example on how to play this game:

Me: TPBM thinks that Nutcracker is better than Rapunzel
Someone else: True. TPBM thinks Melyssa Lyons is the best barbie singing voice
Another person: True. TPBM thinks that....elc

And that's how it is. And if you don't know what TPBM means, I'll tell you: it means 'The Person Below Me'. :)

And... Have fun!
