When a group of people rush to the bathroom at the same time during an event. An example can be during halftime of a sporting event, especially the Super Bowl. Another example is the mass use of bathrooms right after lunch hour in offices.
Fan1: Aren't you going to the bathroom? It's halftime.
Fan2: Nah, I'll wait until after the rush to flush.
