The first thing you do when you walk into a restroom and other occupied stalls. Flushing before you sit down creates enough noise in the area that other people may be able to finish their business while minimizing embarrassment from excessive flatulence.

Seeing as there was only one stall taken, and given the state of his rotting gut, John gave the other restroom occupant a courtesey flush in hopes that he would finish his business so John could get down to his with the added privacy of being the only one in the restroom.

Stopping for a second mid-facial to give your partner a brief moment to swallow.

Things would have gotten messy if it were not for that courtesy flush.

Courtesy flush 

When you double flush a toilet just to be courteous. Not necessarily a double-flusher, just to be polite.
Mostly used in awkward situations.

Matt was meeting his girlfriend Sarah's parents for the first time. They were enjoying a lovely meal when Matt had to take a dump.
This being the first time he had dumped in Mr. And Mrs. Di Carlo he flushed twice even though one should have been enough.
Matt demonstrated the courtesy flush.

The act of flushing a toilet before wiping to minimize the chances of clogging

I went over to Dave's house after going on a date to Chipotle. Needed to courtesy flush to save from the embarrassment.

When you fuck your partner in the ass and cum, then while he/she is taking the cumshit, he/she flushes after the first major bowel movement. At the very same time, you give your dick a good wash and get your dick in her/his mouth one more time. This is actually a double courtesy flush situation.

Oh man, your dick smells, give me a courtesy flush before I stick it back in my mouth, I mean I just gave you a courtesy flush with my first big shit after you came in my ass!

Flushing while shitting. Although this noble gesture is meant to reduce the foul odor of your newly born treasure, there is a personal benefit. If you time this correctly, the turd that's still attached to your ass will get a helping 'pull' from the water below, giving you an extra inch of room your colon.

I shoulda known but the skids in bowl that she wouldn't have the decency to courtesy flush.
