Dick is the German word for fat. Dickmann's are giant (actully they come in different sizes) chocolate covered marshmallows. The name alone makes me laugh every time I see a box. A German friend once bought me one and my blood sugar doesn't ever want me to eat another one.
Haribo is a German candy maufacturer. Have you heard of Haribo gummy bears? They are sold all over the US.
Kindereggs are not just for Easter. They are eaten all year long. A plastic egg containing a small toy is hidden inside each of these chocolate eggs. They are often given to children, hence the name Kinder, as gifts throughout the year.
