so one person picks a topic(doesn't matter) and 1-2 people debate and tell why this topic is bad and make a new topic. You can also argue about the person's debate and make a statement but it can't be you own topic.
Ex: Person 1: girls should join the boys wresting team
person 2: But the girls could get seriously hurt people should make chips healthier
person 3: but girls wrestling could make then tougher and stand out more (is person 3 defends the topic then person 2's new topic doesn't really count)
