We all know the pattern by now. Something minor happens. One of the affected parties doesn't want people talking about it. So they go on a crusade against anyone tha makes a small mention about the thing which ends up making the thing super famous.
It is called the Streisand effect after Barbara Streisand who famously went through such a thing. But for all the fame the effect has, how many people actually still remember what it was originally about, without looking it up?
I certainly don't. I'm pretty sure I looked it up once but apparently it wasn't interesting enough to remember. This just proves once again that ignoring the thing is much more effective than trying to silence talk about the thing.
Kind of similar to the Watergate scandal and all subsequent -gates. I think it's about some spy drama revealing the president's crimes at the Watergate Hotel that led to Richard Nixon resigning but that's about it. And that's probably wrong.
Now that I think about it (I should really get out of this shower) there are probably tons of idioms that are even further removed from their origin. I bet some are so far removed that we don't even register them as being idioms. They're just words.
