Genderflux refers to fluctuating gender identification. This can be done quickly, slowly, or at any speed in between. It's fairly reliable most of the time, although there are exceptions. Genderflux falls under both the multigender and non-binary categories.
How was the Genderflux identity created?
Genderflux took off in 2014, thanks to Tumblr user Deergoths, who applied genderflux to experiences of variation in the intensity within a gender identity (rather than between). A 2016 Teen Vogue article on the changing lexicon of gender and sexuality helped spread the term. While both senses of genderflux are in use, social media suggests Deergoths’ sense is becoming more common, likely to its utility and the existence of the terms nonbinary and gender-fluid. The genderflux community has a rich vocabulary based on flux, including but not limited to boyflux, girlflux, bigenderflux, fluidflux, agenderflux, neutroisflux, nonbinaryflux. A person who identifies as girlflux, for instance, experiences a range of intensity of female identity, while an agenderflux person may experience various degrees of feeling any gender at all.
