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.
