Negatrois (NGT) or negative-gender is a leptrois descriptor of a gender experience that is negatively gendered, or the opposite of positrois, which can include antigenders, negative gender, and gender negativity. It is not the same thing as genderlessness, as someone can be (negatively) gendered. It is also not related with pessimism. Negatrois can be a feeling of shortage/decrease of elements, or a minimal/diminutive gender. It can also be described as a "heavy" gender.
It is not necessarily a neurogender or xenogender, but one may associate or compare their gender negativity with other things such as their neurotype, life experience, lethargy, magnetism, numbers (as in arithmogender), temperature/weather, or other things involving sciences such as physics and chemistry.
