Heheh buba Švabe :D Well they were called both Švabe and Nijemci or Nemci. Nijemci or Nemci was and is old Slavic word for them in general, and means "mute" people. Pretty simple, we didn`t understand them :) . Švabe is regional name, which later was name for all Germans, no matter from which part of Germany they did come. It is not so unusal, that regional name for specific group of people, later become the name for larger part of people.
