Adamasgender

Adamasgender is a gender that refuses to be categorized, and is completely indefinable and indomitable. One can be exclusively adamasgender or not. This term can be useful for those who are put in situations in which they have to categorize their gender, or give a label. One may also use this when trying to explain their gender, as it may feel as though their gender is refusing to work with them, and refusing to be given a label.

History
The term Admasgender 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.

Flag
The admasgender flag was coined by Deviantart user Pride-Flags on September 14, 2015. It has no confirmed meaning.

Etymology
Adamasgender stems from adamas which means invincible in Greek.
