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.

to flush the toilet prior to taking a dump to avoid the smell, sound of embarrising clashing water, (and most of all) the waiting for the feces to go down the pipes.
Ryan- Hey man whyd u pause the game?
Chris- I have to take a dump but i promise to stay in a pre-flush rush mode.
Ryan- Alright good, thanks man.

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!

The act of flushing the toilet immediately after you drop your business in a crowded bathroom, insuring the smell doesn't spread.
