Aromagender is an umbrella term for genders that are validated or closely related to scent, though one can also identify as aromagender itself. Most genders under this umbrella don't use the typical terms one would use to describe gender like masculinity, femininity, androgyny, etc. They instead describe gender through the smell of things.
History
