"Hun snakket som en foss!"

Translation: She talked like a waterfall!

[Agy_O]

Is this a saying in Norwegian?

[majaus]

Yes, it is

[Yakuul]

What does it mean? like, loudly and or unclearly?

[Deliciae]

Incessantly.

[VincentL66]

A waterfall is (hopefully) a constant stream water. So when someone is talking like a waterfall, it will never stop (unfortunately). I thought this was a very common saying. In Dutch we made one word of it: "spraakwaterval"

[AureliaUK]

Foss remains in some northern English dialects and as a place name - High Force, Falling Foss, Thomason Foss.

[KatjaBozarth]

We have the same saying in German. ☺

[JackalopeMoon]

In English there is something similar: she's like a babbling brook.

[Justin86301]

In certain parts of America we would say "she is a motor mouth"

[LiviuDeacu]

In Romanian language we say: "Hun snakker som en knust mølle" (she speaks like a broken mill). Because sometimes a broken mill cannot be stopped.

[kokiri85]

Like, she runs at the mouth?

[PuertoHelenos]

Yes indeed

[Josh_Overlien]

Ironically, I learned about norsklærer Karense from the comments on these lessons and I first learned this idiom from her. I love the idiom, and I used to have a best friend named Sam Foss.

Love foreign idioms.

[m.g.doyle]

Does this mean she talked a lot, or quickly?

[Deliciae]

A lot, and without stop.

[Bertsta]

Did you tell her to holdt kjeft? XD I think that's the term.

[NormanMcDonnell]
