Curtesy Flush 

During the process of a large bowel movement, a "Curtesy Flush" is an extra flush of the toilet to ensure no clogging of the toilet.

Maya was having a large bowel movement after eating authentic Mexican food that required a "Curtesy Flush".

courtesy flush 

A flush in the middle of the toilet-sitting process in order to reduce the aroma...usually performed on a "foreign throne" as a courtesy to the owner of said throne... in other words, to be polite and not stink up the host's crapper too much.

I gave a courtesy flush at the Smith's party because I didn't want to kill the next person to use the bathroom.

When you're using a public restroom and your shit smells so bad you flush it as soon as possible so as not to make everyone else in the restroom puke.

Hey, how about a courtesy flush?

Flushing the toilet at the exact moment of a smelly bowel movement hitting the water as to minimize lingering oders that may eminate off the perpatrating poo. Keeping the bowl poo free will keep the bathroom odor to a minimum.

Autumn Courtesy Flush 

A process carried out by university administrators in the Autumn term which involves shedding students who don't turn up regularly to classes to ensure they aren't charged fees and become an unnecessary financial burden to the institution. This is performed by the student being summarily "deregistered" on the grounds that they are "inadequately engaged" on their programme of study. As a result, students find they are suddenly unable to submit coursework or access any university facilities whatsoever, thus providing proof that they are indeed no longer engaged.

Chris the student: Hey professor! Why can't I submit coursework or access any online library facilities in order to complete my term papers?

Professor: You've probably become an unwitting victim of the most recent "Autumn Courtesy Flush."

Chris: What's that?

Professor: You've been deregistered because you haven't been coming to class.

Chris: My God! But if I can't submit assignments I'll fail the year.

Professor: Yes, well you should have thought of that, shouldn't you? Anyway, good luck with your career.
