Agatic describes a woman, or feminine aligned person, who is wlw and wlnb, meaning a woman who is attracted to women and to non-binary people, and/or a woman who prioritizes her attraction to women and non-binary people over other attractions she may have. This attraction can be exclusive or not. Agatic is an umbrella term, like sapphic, and is typically not used as an identity on it's own, however it can be if desired. People included in this umbrella are pansexual women, bisexual women, and any other women who are attracted to women and non-binary people.
Flag
The flag was created by Tumblr user Saturnic-vapour, who is now deactivated. The flag was likely made some time around June 24, 2018. The colors represent the colors of agates. The red orange and yellow also represents love between women, and the blueish grey represent love between women and non-binary people[1]. The term itself was coined by an anon, likely on Saturnic-vapour's blog.
