Evongender

Also shortened to 'evon', a non-binary person whose non-binary gender fades in and out to the point of being in a genderless/agenrine state, like in the water cycle. Any non-binary gender can be used with this label. It is also known as 'evenby', and is a sub label of evagender. Two of evagender's other sub labels also fall under the evongender label, which are nuvogender (nuvo) and mevogender (mevo).

History
The term was coined by tumblr user nonbiarrow on July 3 2021, with the flag created on the same date by the same person, as well as nuvogender and mevogender.

Flag
The black respresents the genderless/agenrine state as the person’s gender has faded away, the fading yellows show the non-binary gender evaporating up into the sky and then coming back up through the ground like in the water cycle.
