When a young Black man doesn't like to associate with other Black people and would never go out with a Black girl. He behaves like a White person, has White friends, always dates White women. For all intents and purposes is Black on the outside, but White on the inside.
"Holden would never date a Black girl. He prefers White girls."
"I know, he's a total Oreo cookie."
