I’m going to copy and paste the definition the coiner gave, since it's somewhat different:
“Its both a gender and orientation.
As a gender it’s “many but not all” and is something that circles the spectrum but is also an outlier. Maybe some gender feels are stronger at some point, maybe another, but never predominately.
As an orientation it’s again, simply “many, but not all” so like pan but the not all is more of a choice. Like, I like all genders but I choose to disregard my attraction to men bc of society.
These labels are free for anyone to use esp ace/aro spectrum folk!”
Here’s what the flag colours mean:
The flag colours represent the gender binary and all genders in between. Moreover, they go to show how even binary genders are more than what meets the eye.
