"Sjonge jonge jonge". The most common sentence in Dutch that I don't understand yet. :)
Google translate says it means "Oh yes young" If I put "Tjonge jonge jonge" in Google translate it says it means "Wow young". Either way doesn't make much sense to me but the natives say that it has no real meaning, it's more of a shake your head while muttering "Oh, the young people's behaviour".
