"Goblin mode" is to engage in antisocial behavior that goes against society's norms in an often sleazy way.
The expression does not exist in Swedish, but goblin is most closely translated as "wet" or "troll" - a cave-dwelling fantasy creature characterized by making a mess.
The Oxford English dictionary is the third English-language dictionary to launch the word of the year in a short time, and all of them seem to reflect that we live in dark times.
Merriam-Webster chose "gaslight" and British Collins' word of the year became "permacrisis".
