Genderspike

Genderspike is a gender in which one is normally a given gender, but very occasionally experiences occasional, sudden, and short spikes of a different gender, before returning to one's normal "base" gender. The gender one spikes too may or may not be the same every time. The base gender can be any gender or combination of genders. The spiked-to gender can be any other gender or combination of genders. Genderspike can be combined with other relevant genders. For example, a neutroisspike person is normally neutrois, but experiences rare spikes of another gender or genders.

History
Genderspike was coined by an anonymous ask to beyond-mogai-pride-flags on June 27, 2018. Several genderspike flags were created by Tumblr user Spicydiscovery (deactivated) on or before July 7. 2018.
