The translation from Swedish to English never works too well because the sounds you make are often times just too different. Ive been sitting here for a few minutes trying to write out bergman as you would say it in swedish but i cant get it right lol.
As for something you can say in Swedish...hmmm...(maybe just text it or something if u cant figure out how to say it)
Du har tur du hittade en man som jag
(you are lucky you found a man like me)
not too long or hard to say, maybe use as a neg
Norska tjejor är snyggare än dom svenska i vilket fall som helst
(norwegian girls are hotter than the swedish ones anyway) Use a regular a for the ä)
Swedish and norwegians always shit on each other for everything kinda like polish jokes so this might be a funny neg if she knows her stuff.
Ill think of some more tomorrow its late im tired good luck bro
