Banana is a mildly pejorative term used to describe people who are "white" (Western) on the inside and "yellow" (of east Asia) on the outside. It is particularly used to describe women who have become highly assimilated into Western culture and/or married Caucasians. It is usually used to refer to people of east Asian origin living in Western countries (e.g. Asian Americans ).
It is commonly used by Chinese Americans to refer to other American-born Chinese. It is also increasingly used by native Chinese to described Chinese Americans. It is a synonym of jook-sing.
Banana Boys is a novel by Terry Woo about a group of Chinese males recounting the past and bringing to light issues they faced while growing up in Canadian society.
The opposite of the term "Banana" is "egg" - a white person who acts as a person from east Asia.
