The word "Häagen-Dazs" has no meaning in any language, although it is widely thought to be Scandinavian. The ice cream brand was created by two Polish immigrants who came to America, but the name is simply two made-up words that are meant to look Scandinavian.
The real origin of the name is a reversal of the name "Duncan Hines" an original potential marketer of the product, which became "Huncan-Dines." The name was reworked to sound scandinavian and became "Häagen-Dazs."
