As noted above... Germans and "gypsies" have not been a happy, historical-homogenius mix.
The term is excluded from most older (1910-1970) dictionaries but may be found underGIPSY and referenced to the USA. Zigeruner, Zigerunnin
My favorite is the adjective Schwannspinner /i> what a wonderful, visual!!!

pump that last term into Yahoo...interesting?
