Banana, coconut, and Twinkie are pejorative terms for Asian Americans who are perceived to have been assimilated and acculturated into mainstream American culture. In Australia, South Africa, and the United Kingdom, coconut is similarly used against people of color to imply a betrayal of their Aboriginal or other non-white ethnic identity. The terms derive from a perception that a person is "yellow [or brown] on the outside, white on the inside", or is "acting white".
