Adeptogender is when your gender identity was obtained through your realization of your kinself. as in your kin realization spurred your gender realization. (note: the gender and kin type do not necessarily have to correlate with each other).
The term adeptogender seems to have been first coined on a site that mocks non-binary people, however this site was taken down. The terms coined there were reposted by the Transgender Teen Survival Guide on December 26, 2016 and have been used in a better light since. It is unknown if the person who posted these terms was aware whether or not the site they posted them on was offensive.
The flag was created by wiki user Anya111 on October 29, 2018. The brown stands for animals, pale stands for the realization, and green stands for any gender.
