A hecatolic individual is attracted to non-binary individuals and/or prioritizes their attraction to non-binary individuals over other attractions they may have. Hecatolic is an umbrella term, like diamoric, though it can also be used as an identity by itself.
The term hecatolic was coined by Tumblr user Imsureitsalltrue, through an ask to the user Nbandproud on July 14, 2018. The flag was designed by Saturnic-vapour, some time around September 7, 2018. The colors are based off the gemstone hecatolite, also known as a moonstone.
