Also shortened to 'evir', an evirgender person is a man/mingender person whose manhood/masculinity fades in and out to the point of being in a genderless/agenrine state, like in the water cycle. It is a sub-label of evagender.
The feminine/female equivalent of this is everagender (evera).

The black respresents the genderless/agenrine state as the person’s gender has faded away, the fading oranges show the masculinity/manhood fading up into the sky and coming back up through the ground, like in the water cycle.[1]
