Aggelos

Aggelos is a neurogender that is an angelic gender that presents as masculine or feminine in a softly binary way, but that’s only the gender’s presentation. The true gender is a heavenly gender that cannot be described with words. The term can be used by anyone, but it is preferably used by those who have delusions and believe that their delusions of divinity or angelicism come into play with their conception of gender.
