courtesy flush 

1. Flushing the toilette more than once and ASAP to reduce the unpleasant scent of your own turd(s).

2. Something you had better do when you are in jail or prison, so your cellmate(s) don't/doesn't give you a beatdown. LOL!

3. If it smells bad to you, how much worse will it smell to the other person if you don't have the common sense, or the decency to do a courtesy flush.

Redneck/Jail/Prison definitions:

EX: Dude! Could you at LEAST do a courtesy flush!?!?!?!?

EX 2: If you don't do a courtesy flush you'll be getting a blanket party tonight!

Ex 3: If you don't want a swirly. gimme a courtesy flush over there.

This type of courtesy flush is usually performed at home. It's showing courtesy to your family by not leaving any fecal remains in the toilet after you have taken a shit.

A courtesy flush should be performed after the initial flush if there is fecal matter still left in the toilet, or there are skid marks left on the bowl. Repeat as necessary.

I went into the bathroom after my grandmother, and she never courtesy flushed. Infact, it seems like she never flushed at all.
