gaijinshi

A derogatory term that describes a style of art, be it drawn, animated or otherwise, that emulates anime and manga but is neither produced in Japan or by a Japanese person.

The term is a combination of the words gaijin, which means foreigner, or (more accurately) "non-Japanese", and doujinshi, a Japanese word for amateur-produced comics.

The term is used mostly when referring to the massive amount of embarrassingly poor drawings that are uploaded to the deviantart community by wapanese nerds. However, it can also be used to describe professionally produced comics and animation. Examples include the comic “The Boondocks”, and the cartoons “Teen Titans” and “Avatar: The Last Airbender.”
