a kind of melon that creates enjoyment for Germans (hence the wasser bit) and Japanese (merron)alike. They are often so greatly pleased that they shake their arms about in a gleeful fashion.
A JAPANESE MAN: Hello Gunter, how would you like some wassermerron?
GUNTER THE GERMAN: Ja ja!
then a lot of rejoicing goes on. Hoorah!
