Lots of places actually invent languages to make themselves seem more "special".
Welsh, for instance, started off as a joke to play on tourists using all the left-over consonants that they had when making road-signs. But then it caught on and they had to try and make a language up in retrospect to match all the signs which is why no one can really speak it.
Interesting fact: They got a little-known (at the time) language student to create Welsh. His name was John Ronald Reuel Tolkien, yes, the same J.R.R.Tolkien who wrote Lord of the Rings and The Hobbit. Inventing Welsh inspired him to invent Elvish and then make up some books where he could use it.
Is that like a trump style fact? Tolkien took his elvish language from Welsh. Welsh has been around for centuries. And people can speak it.
