Well, in Norwegian I can suggest the following (with English equivalents - not necessarily literal translations, but degree of foulnes):
Dæven - "holy shit". Literally it means "the devil" in a slightly modified writing, but it is used to express that you are surprised, scared or impressed - rarely used to express anger.
Pokker - "dammit". Not very harsh, it is usually used as a milder alternative to:
FAEN - equivalent to the F*** word in English, also derived from a word for the man with the horns
Then of course we have
HELVETE .- just a translation of Hell. On the funny side, I can add that the word "hell" in Norwegian means luck. I can also add that Hell is small place 30 km east of Trondheim, where I live. Trondheim Airport is located just 1 km from Hell and it has been suggested the airport changes name to Hell International Airport
More funfacts, there is an actual place in Norway called "Helvete" as well - it's a place where some of Norway's deepest giant kettles are located. In the mountains some kilometres north of "Helvete" there is a place called "Himmerik" which means Heaven. There is an annual race from Helvete to Himmerik
Oh, I have made a big digression. I should pick a song.
The Nomad it is.
