the poster makes a statement about someone and the next one has to say whether it's true or false and then he/she has to make a new statement...
For example, I would say:
The person below is a female...
And the one who replies says whether its true or false.
and then she makes a new statement, for example:
The person below has a pet dog...
And so on... :)
