Gendernull (also called nullgender) is the absence of gender, but it is not agender or neutrois. It is a term for those to give a “tangibility” to the intangible thing that is their gender.
Gendernull has been described as: "Undefinable, intangible, the uncreation of gender. Its taking everything everyone throws at you, saying male, female, pick one, pick this, pick that, and taking it in, only to expel it, poisonous crystals erupting from your skin, armor against those who don't listen. A 'I don’t want a label because labels don't fit but they help shut people up sometimes, so here have a label' gender label. A fall-back plan, a red herring to give people who can't conceptualize the absence, void, nullification of gender. It is, and is not. All and none. Nonexistent but present."
Gendernull is similar to, but not the same as, agender, neutrois, and gendervoid, and is often considered to be a part of the same spectrum. It is also a part of the kenochoric umbrella.
