In German, "Mist" is a
slang word, which means "manure". Many companies have had
problems marketing their products in Germany as a result of this. Clairol,
for example, experienced difficulties when trying to launch their "Mist
Stick" curling iron in Germany. They soon discovered that
there was not much demand for a haircare product called "Manure
Stick"!
Rolls Royce had similar problems when marketing their "Silver Mist"
car. In this case, the company resolved the problem by renaming it "Silver
Shadow".
The Irish alcoholic beverage, "Irish
Mist" did not sell very well in Germany either.
