Media Markt has a campaign where they state that the world belongs to the "Unblöden", but I don't understand what "Unblöden" means and Google translate won't translate it.
So what does "Unblöden" mean?
Well Media Markt has the slogan
which means as much as "I'm not stupid at all!". The meaning is that people who buy at Media Markt are not stupid.1 "Unblöd" is a madeup word for the opposite of "blöd".
"Die Unblöden" are the people who are "unblöd" – something like "the non-stupid".
1 Even if I sometimes think the opposite might be the case.
