Rush 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.

Flush Rush 

When you take laxatives and ipecac and then engage in sexual intercourse. When timed correctly, you both orgasm, vomit, and defecate simultaneously and fall asleep in a steaming morass of your own filth.

Could we please not get a motel room that smells like it was just the scene of a flush rush?

Ryan- Alright good, thanks man.

Rush to flush 

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.

When you're taking a piss and you flush before you're done pissing and you have to finish before the toilet is done flushing. Many have made contests out of this and a scoreboard is recommended. DUDE GAME!
