Fizzgender is a term that falls under the Xenogender umbrella. It relates to fizz as a metaphor. It is a gender that feels is contained in an area, but is everywhere in that specific area, running around rampant. An example is if you pour soda onto a surface. All the bubbles are contained in the liquid of the soda, and sometimes the bubbles would exit the area of the soda, but not often, relating to how sometimes someone who identifies as Fizzgender can feel like they are genderless or don't feel certain with it. Fizzgender is also very fluid, as soda is a liquid.
History
The term Fizzgender was coined on July 9th, 2021 by Pfyaein.
