Yeah it's just a placeholder and I used it and saw it in use a lot before, specifically meow...
Anyway yeah if means strong_ordering/weak_ordering/partial_ordering.

Did I miss something (and seemingly the entire internet, since Google
returns no results for "meow_ordering") or is "meow_ordering" not a
thing/referring to something else ?

I found this really confusing as well, and spent longer than I would care to admit trying to google it. Eventually, I realized that "meow" is a cute way of saying "foo" or "bar", and used the context clues around the `<=>` operator to realize that they were likely referring to std::strong_ordering, std::weak_ordering, and std::partial_ordering.

Once I figured it out, I decided not to reply. But maybe that was a mistake. If you found this confusing, and I found it confusing, then I'm sure many other people on the list did too.
