The opposite of "coming to order" is "descending into chaos". When a meeting or event is coming to order, it means that people are settling down and preparing to begin in an organized and orderly manner. However, when things start to spiral out of control and people become unruly or disruptive, the situation can quickly devolve into chaos. It's important to establish clear rules and guidelines for behavior at the outset of any meeting or event, and to have a plan in place for dealing with any disruptions that may arise. By doing so, you can help ensure that your gathering stays on track and remains productive.
