Can refer to either of two "throne-based" occurrences:
(A) An embarrassing event which causes red-cheeked humiliation ("flushing") to The Crown, such as Charles and Diana's rocky/brief marriage after such a lavish/heavily-hyped wedding, their subsequent affairs, and Di's suspicious/untimely death.
(B) A humongous porcelain-bowl rinsing with abnormally-copious floods of H-2-0; it involves filling two or more buckets or other sizable vessels with water, raising the toilet-seat and removing the tank-cover, and then recruiting one or more assistants with strong muscles (AND strong **stomachs**!) so that you can then both hold the toilet's handle down and quickly pour additional water into the tank and down the bowl at the same time, creating a massive torrential swirly that is far more voluminous and longer-lasting than usual. This extreme measure can indeed be **sometimes** effective for clearing a plugged toilet-drain, but it can also messily "backfire" (i.e., send filthy stinky water cascading out in all directions) if the clog decides to be extra-stubborn --- user-discretion is strongly advised. Use of liquid/gel drain-opener is not recommended here, either, in case of said "backlash", since the errant drain-opener can cause severe burns and/or property damage.

My toddler-nephews love to spool off yards of tissue and toss it down the crapper when they come to visit, and so the wife and I are always obliged to give the guest-room toilet a royal flush after they leave.

When you are on the phone so long with tech support that you HAVE to go to the bathroom. It's #2; you can't just leave it there because your housemate will be mad. Even though it's tacky, you just wipe and flush, even though you are well aware that the tech support person can hear the toilet flush.
I was on the phone 3 hours today with tech support, IRS and couldn't hold my poop any longer, so I just did my business and support flushed while he was talking to me.

I got into the stall at the restaurant and had to do a reverse courtesy flush for the guy before me before I could drop my own deuce.

He went 0 for 4 at the plate last night. He really “flushed the mouse”. They really “flushed the mouse” when they lost by 31 points. He was on his dream date and “flushed the mouse with her by acting like an idiot. No second date for him.

"I don't think you should be hitting on them, they look like a royal flush."
"This is a royal flush household and thus sex is frowned upon."

Someone who, when using the toilet, flushes over and over, often, each time a turd is passed. Sometimes curteous in public bathroom settings, but often times wasteful of both water and more often than not, toilet paper.
