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.

The act of flushing the toilet immediately after you drop your business in a crowded bathroom, insuring the smell doesn't spread.
Girl 1: Damn, that was a long one, thank god I rush flushed in the bathroom.
Girl 2: Yea, before all the other girls in there could smell it and start laughing when you walked out.
