Cast your mind back about 20-25 years or so. Back in those days some zoologists announced to the world the Tigron and the Liger. So named as they were cats that came from mixed breeds. The Tigron had a tiger father and lion mother. The Liger had a lion father and tiger mother. It got me thinking what do you call children of mixed-race couples? I've come up with a few suggestions. Let's just assume that the terms white and caucasian along with African and black are interchangeable.
Whipanic - White father, Hispanic mother
Hishite - Hispanic father, White mother
Whack - White father, Black mother
Blite - Black father, White mother
Whitesian - White father, Ploynesian mother
Whasian - White father, Asian mother
Asiite - Asian father, White mother
Jewesian - Jewish father, Ploynesian mother
Afropanic - African father, Hispanic mother
Hisfro - Hispanic father, African mother
That's as creative as my brain lets me be this morning. Let me know if you come up with any more.
