Octoroon
A human with 1/8 black blood. Basically a half-assed mulatto who got lucky.
My cousin is an octoroon. People think he's white, but he's got the genes of a confused ancestor.
She's got 1/8 black blood. Her mom said she was 'too white to be black, but too black to be white.'
He’s an octoroon. He’s like a quarter mulatto, but with less effort.
