Spikegender or Burstgender is a gender that is mostly undefinable. However, one occasionally experiences sudden and intense spikes a specific gender that last a relatively short time before returning to one's normal undefinable gender. One can experience any genders or combination of genders during these spikes, such as boy, girl, non-binary, etc.
