Sparkgender

Sparklegender is a gender identity where one is normally agender/genderless, but they sometimes experience "sparkles" or "bursts" of a gender. When these "sparkles" end they return to being agender/genderless. These "sparkles" can be any gender or gender identity, and they don't always have to be the same.
