A friend of mine flipped out when he thought I said farsa (~dad/pops) and he wondered where I learned it from. It was actually just another word from Austin Powers, but still.

Agree with Anton, "rajtantajtan", used that one with any Swede you'll meet!

Spunk: If someone is raging or irate, you can say that person got "spunk".  

Dratta: When a person fall.

Fejjan: A "slang word" for face or Facebook.

I think these sounds fun! :)

Rajtantajtan - as in party, not that alot of people uses it but it sounds funny :)
