Butter Goose

Me: What's the Swedish word for bread?"

Him: Bröd. 

Me: That's what I thought, but I was reading a thing today where both the German and Finnish words for sandwich translate literally to "butter bread." And since "smör," means butter in Swedish, then gås is...?"

Him: ...goose. 

Me: Goose?

Him: Yes.

Me: Butter goose?

Him: Yes. 

Me: The Swedish word for sandwich is butter goose?

Him: ...yes. 

After furious Googling: 

"Smörgås in turn consists of the words smör (butter, cognate with English smear) and gås. Gås literally means goose, but later referred to the small pieces of butter that formed and floated to the surface of cream while it was churned.^[3] These pieces reminded the old Swedish peasants of fat geese swimming to the surface." (Wikipedia)

Me: So, actually the Swedish word for sandwich is "butter butter."

Him: ...yes.
