Перевод - Шведский-Английский - hejhej jag äger mest av alla

Hej hej kan ju betyda hej också. Inte bara Hej då. Så "Hello I own most of all" eller "Hi I own most of all"

hur blir "hejhej" ett "bye" ?

This is kind of slangy. I translated once (according to Porfyhr's tips) as "It rules/rocks/etc.".
I think it should read "I am the best amidst you all".

Hi Casper,
Would this mean
I rule
?

Let's wait till the experts come back.

Here:

Äger motsvarar väl engelskans slanguttryck rule: "Han äger", "he rules".
Äger correspond to the English's slang rule...

Agree that "Han äger" also is "he rules" in slang, but we don't know here IF this is a slang expression or not. "äger" is also correct translated by johanna (own).

Maybe a remark/alternative text in the notes?
