A Native American whose behavior is too white is sometimes called an apple- red on the outside and white on the inside, get it? A black person who behaves like a white person is sometimes referred to as an oreo- black on the outside and white on the inside.
I’ve tried hard to think of something which is white on the outside and brown on the inside, unsuccessfully. Other than myself, I mean. Can you help?
I think thats just called a wigger. No food metaphors that I’ve heard.
Twinkie - yellow on the outside, white on the inside.
Oreo/coconut - black on the outside, white on the inside
Apple - red on the outside, white on the inside
To my knowledge, I don’t think these food metaphors go in the opposite direction. We just have terms for them like weeaboo, wigger, etwc.
