Nymbinary Pride Flag

Nymbinary (nymby) or abinby (abinbinary): a binary aphorian, a person who identifies as a binary in a way removed entirely from the gender binary system. It is a type of binariness that is abinary in nature (ABIN), and therefore lacks ties to the gender-binary, including a relationship to aptobinary genderedness (aptobinariness/aptobinaryness) or ambinariness/ambinaryness, (fe)maleness, (wo)manhood, boyhood/girlhood/birlhood, (fe)male-alignment, binary masculinity/femininity, and most other widespread connotations of binary-ness. Nymbinaries (nymbies) may even see their binaryhood as anonbinary or something else entirely.

Could be an umbrella for nymboy and nymgirl.
