https://en.wikipedia.org/wiki/MiscegenationBasically, an apparent legal term term for racial mixing, inter-racial couples and inter-racial children, for which there are Miscegenation laws to prevent.
Till now I'd never heard the term.
Till now I'd only heard the terms "mixed-race" or "mulatto" The latter appears to be a latin-American term for people who are a mix of white and one or more other races.
https://en.wikipedia.org/wiki/Mulatto Which either has become, or always was, an offensive pejorative term.
I came across
Miscegenation in a Youtube comment where they listed a Twitter hashtag of:
#MiscegenationNation
A few others she had in her post were BBW (Big Beautiful Woman, women weighing upwards of 200 pounds)...
https://en.wikipedia.org/wiki/Big_Beautiful_Woman...and SSBBW (Super Size Big Beautiful Woman). That are not only terms, but are search categories of porn!
Somethin' out there for everybody, I guess...
