Horbarn

In Sweden it is a custom to say Horunge to someone when you are mad or when you want to lay an oath, but when you get excessively mad you'll need a new word. The word that fits this kind of anger is 'Horbarn' which is, directly translated, swedish for Whore's child, basically the same meaning as Horunge but should be used not when you're mad and upset but when you are furious.
