Hi Leo, the word has been in use in Norwegian since 1911. The word appears in Danish editions of books from 2001, as in the paperback version of this.
A link to a website is not a citation. The website gives no date or source. Our WT:CFI requires that words be citable in durably archive media. Also, you still have not indicated which languages you speak, and the list seems to be growing. If you continue to edit in languages that you do not speak, you will be blocked. --
