How do you say oh really in German?

Answer 1

oh my gosh is a minced oath version of oh my god. The latter would be Oh, mein Gott! in German, the former can't be translated, but you could use a rough equivalent.

Ach, du meine Güte.

Ach, du heiliger Bimbam.

Answer 2

its 'oh gut'

Edit: "Oh gut" if you wanted to say it like "Oh, good." If you want to say something like, "Oh well, better luck next time," then you would probably use tja (closer to oh well in a reassuring way) or naja (pretty much the same thing but closer to well)

Answer 3

oh wirklich
