Estrialgender is a gender for when one does not identify with Earth’s human gender binary due to being from another planet. One can also identify with a gender from another planet.
The term was originally known as aliengender, but that term already existed so it was changed to estrialgender (Estrial from extraterrestrial).
History
The term was coined on January 16, 2018 by an anonymous tumblr user on Ask-Pride-Color-Schemes. The specific estrialgender flags were all designed by tumblr user almighty-hall, though those resources have since been deleted.
