That would be the infamous Icelandic verb of "nenna". It's used as such "Ég nenni þessu ekki", which translates roughly to "I don't feel like it" or "I don't want to".

But we have a word for both want and feel like, but they're different from "nenna". In some ways a better translation would be "I can't be bothered to".

The word is somewhat socially acceptable as an excuse not to do something.

"Þetta reddast" and "Ég nenni þessu ekki" are words many of us Icelanders live by.

Probs something like ‘nei, nei, ekki’ which means ‘no, no, don’t’.
