Egg (person)
An egg is a joking term for someone of Caucasian extraction who shows more interest in Asian culture (especially East Asian...Chinese, Japanese, Korean, etc...) than Western culture, or who "acts Asian." This may include interest in Asian languages, dress, history, habits etc. The term uses the food motif of the more common banana, which describes the inverse: a person of Asian heritage who is more interested in Western culture.The metaphor has to do with racial colors: a banana is yellow on the outside, white on the inside, and an egg is white on the outside, yellow on the inside. A similar metaphor is used for black people who "act white": Oreo.
While the term egg is usually one of pride for the egg in question, other terms involving the notion of acting like another race can range from mildly to highly pejorative. It ties in with complicated issues like racism, separatism and notions of racial betrayal.
A term related to egg which is pejorative is the term Wapanese, which is based on the expression Wigger. Wapanese deals specifically with a white person who is obsessed with Japan, often especially anime, and imagines him or herself to be an authority on Japan, yet may lack a real understanding of or respect for Japan. Wapanese tend to be middle class white teenagers or college students who feel alienated by Western society and imagine that they would be accepted in Japan.
