Just post something that is unacceptable to you. Then the other player continues (hope this works).
I start:
I think it would be unacceptable if a friend of yours invited you to spend christmas Eve to his house and you get there, eat, drink, and at about 12 o' clock you say: Go to hell! and leave.
it would be unaceptable to jumo up in the middle of class, scream i like pancakea as you kill the teacher, glue the students to one another, throw them out the window, and then eat cheez its.
