Theoryfeminine is a gender that is connected to femininity in some way. It is based on the American English phrase "in theory" which is used in describing what is supposed to happen or be possible, usually with the implication that it does not in fact happen. In theory, one's gender is feminine; in practice, it may not be. Can be shortened to Theoryfem or Theoryfemme.
