a negative term used by both
black and white people against a black person who hates the fact that they are black and wants to be white. many female oreos (happens with males too, just not as much) use skin-bleaching products for lightening the tone of their skin. most oreos also
believe that they are better then other
black people and think they all are beneath them.
commonly mistaken for an oreo is a black person who 'talks proper', or uses correct grammar, gets good grades, has white friends, listens to music genres other than rap and r&b, etc.
