Geminigender is a zodiacgender based on the constellation Gemini. It is described as a gender in which one is mostly/usually agender, but one's gender will occasionally change to a different indescribable, nonbinary gender. These changes can be rare or often depending on the person. The amount of time each non-binary gender lasts also varies. What the non-binary gender is changes each time. Every time a gender surfaces, it is unique and will eventually go away, never to return. It relates to Gemini in that it is typically stable, but will occasionally have significant bursts of changes.
Geminigender can also be used to describe any gender that is in some way related to Gemini.
