Genderfrither is a form of genderfluidity in which someone is only fluid between genders that are in some way connected to masculinity or femininity, but they are never completely male. A genderfrither person never experiences genders that are completely abinary (removed from masculinity or femininity), and never experiences being a binary man, though they can be a binary woman. For example, a genderfrither person could experience genders like woman, androgyne, demiboy/demigirl, proxvir/juxera, libramasculine/librafeminine, etc. They would never experience genders like binary man, neutrois, maverique, agender, etc.
The first apparent mention of genderfrither was on the Gender Jargon list by Tumblr user Gender-Resource's on April, 2020. It was coined on UncommonGenders via Tumblr on an unknown date..
The flag uses the colors representing female from other fluid flags, and a purple-blue version of the colors representing male to represent masc genders.
