Well from a reddit post of this on r/comics, there is some discussion on what the words mean. Here's the basic conclusions:
"Speaking of mixing northern tongues, ø and ö is the same letter just that one is the norwegian way to write it and the other the swedish way. They are variants of each other, but the use, meaning and pronunciation is the exact same."
"It's just as much gibberish in Norwegian as it is in English.
Maybe even more, seeing how as a Norwegian I know that "ø" and "ö" is the exact same letter with the exact same pronunciation, just that the former is Norwegian and the latter is Swedish. Makes it more obvious that it is just some random gibberish, and does not actually mean anything."
