Cupishipgender
Cupishipgender is a xenogender identity in which one's gender is related to the ship (usually a romantic pairing between two fictional characters) that one is projecting oneself or their relationship onto at the moment.
Cupishipgender may be used in conjunction with other xenogenders, (ie. X ship makes you feel more catgender, Y ship makes you feel more ghostgender), or as a stand alone where your gender is influenced by projecting yourself onto ships, but doesn’t change your gender identity depending on the ship.
