So a while back, I asked for your help with some Norwegian slang words. Thanks to you, I was able to compile a list with a bunch of others I found and already knew. Some of these words are also dialektord, or only used in a specific dialect, not standard bokmål/nynorsk. The words in bold are ones which I didn’t know (feel free to translate)!

And for everyone who submitted a word, you’ve been linked!

If you have any words you’d like to add or corrections, please leave a comment! This list will continue to grow and will be added to the Guide + Resources page.

EDIT: I have also added a bunch of text messaging jargon from the book Teach Yourself Norwegian.
