Why are people talking about flying a flag upside-down?

Today, a bunch of people on my Mastodon feed are making declarations about somebody apparently flying a flag upside down, and this apparently has something to do with the New York Times being terrible....

Flying the US flag upside down on ship is apparently a distress signal.

(Flying the UK flag upside down just makes people think you’re an idiot.)

Does the UK flag even have an “upside down”?

Yes.

In the upper corner of the flag nearest the flagpole, the wider diagonal white stripe should be above the red diagonal stripe. If the red is above the wider white stripe the flag is upside-down.

Wow, that’s so subtle!
very much so, just look at the corners

Oh boy, you’re possibly in for a treat. I didn’t notice this for far too long either, but the UK flag is at a complete wonk:

It’s got rotational symmetry, but if you just flip it vertically, the thin red stripes will be the wrong way around.

See, that’s where I was confused. Since it has rotational symmetry, I didn’t notice, since I just took an image and rotated it— but it didn’t consider how a flag hangs from a flagpole, with one edge having eyeholes for a rope or string. This means it would be inverted, not rotated, and the stripes would be different.
