Today I learned that "home names" aren't a thing for most people and I'm shook like do most people not have a hidden name??

Poll: Do you know what a home name is and do you have one?

Explanation for what a home name is because it's not the same thing as a nickname and that seems to be people who don't know what a home/family name think it is: https://twitter.com/gideon_ismail/status/1245780229349490688?s=20
