It's quite funny for me, because (from the article) in Slovene the dialect is refered to as "kočevarščina".
I don't know Slovene, but I speak one of the Slavic languages and it sounds to me as "cat's growl".
Not very nice maybe, but we're talking about meanings long lost in time.
We call Germans: "Niemcy" and it comes from the word "niemy", which now means "mute", but used to mean "foreigner" in proto-slavic. We don't think of mutes when meeting Germans tho. We never did.
Of course no ill will intended here. Just a bit of history perhaps.
