Memorgender

Memorgender, also known as forgorgender is a gender in which one feels as if they've temporarily forgotten what their gender is. The gender feels empty because one is unable to identify it.

Memorgender is similar to, but not the same as Gendervoid and Gendernull.

History and Flag
Memorgender was coined by Reddit user Jaz_ismybrand2 on August 30th, 2021. The flags were made by the same user on the same day. The gray stands for genders you've forgotten, blue/green stands for remembering, the black stands for the lack of gender/the emptiness of the gender when forgetting, and the purple stands for trying to remember.
