Kykosgender is a xenogender defined as a combination of mothgender and gauflux, where ones gender feels like it matches the cycle of the day and night outside.
For example, during the day one could be a boy and at night one could be a girl, but when it is darker, one is more likely to be demiboy or demigirl. Dusk and dawn are commonly flux and demigender times of the day.
History
Kykosgender was coined in the summer of 2020 by fandom user Stitchy0 on his tumblr account which is now deactivated.
