genderfluid between (a) non-binary gender(s) and gendernull.
The static equivalent is Nullenby, the neutral equivalent is Neutranullfluid and the androgynous equivalent is Androgynullfluid.
The term Nullenbyfluid was coined by tumblr user nonbiarrow on May 9th 2021, as well as its flag.
The flag shows five stripes: the grays and yellows represent gendernull and non-binary genders respectively. The variation of gray and yellow stripes show the gender's fluid nature and the light yellow stripe shows being inbetween or both/all genders.
