@Stoori @eclectech Now that I started to think about this, I agree, it is really difficult to say if one phrase is more common or iconic than others.

'No voi jumalauta' is actually pretty good! I was also thinking 'No voi saatana', or 'No voi vittu' or any other nasty word 🤭

I don't know why it feels more like "for fuck's sake' when there is 'No' at the beginning, even though it is more like 'Oh' in 'Oh, for fuck's sake'.

If someone needs inspiration or a demonstration for frustrated, angry, exasperated, "slightly" sweary expressions in Finnish, there is always this classic: https://www.youtube.com/watch?v=xuywUEdkvTM
