There's a lot of exotic languages out there, but the folks at The Local Europe have gone viral with one particular word they have come across.
Swedish for "yes" is "ja" - not particularly strange. But in the northern parts of the Scandinavian nation, they use a very odd sound instead.
We're not sure how you'd spell it, but it's basically a little "shoop". Which is really, really weird but also quite cool.
