"Ufda" is a phrase commonly used here to mean something along the lines of "that's too bad" or "how unfortunate," with undertones of sympathy (like when you would say "ouch"). The spelling is kind of besides the point, because it is generally a spoken phrase.
But if folks want to get really picky about authenticity, and apparently they do, "Ufda" is how my Norwegian friends spell it in text messages. Although, I am sure alternate spellings would be acceptable too.
I meant it here to say simply that it was too bad this guy got arrested, with undertones of sympathy and a bit of Scandinavian solidarity. Norway and Sweden are only jokingly rivals, but are actually very friendly.
Something obviously got lost in translation, probably due to the American-centric nature of this forum.
