German-American 

1.) An American citizen of both German and American descent
2.) An American citizen that can trace his/her heritage back to both Germany and to the colonies of the United States

A German-American has both German and American blood. The term German-American, as well as other hyphenations in America, is commonly used to signify an American citizen of German descent. However, according to international standards, this is incorrect. A true German-American is of both German and colonial American descent.

"Look! Lars is watching MTV and eating McDonald's yet has a bumper sticker that says 'If America is the land of the free, I'd rather be enslaved.' Typical German-American paradox..."
