Neurohoarder is a term for when one is always questioning their identity due to neurodivergence, and may hoard a number of labels for identities such as pronouns, names, genders, orientations, etc. Could be considered a neurogender, and/or a subset of genderhoarder.
Flags
The original poster says they referenced the nebularomantic flag for the shades of color and number of stripes. The purple is pulled from the genderhoarder flag and slightly adjusted, the blue is from the nebularomantic flag (along with blue being quite common in quoi- flags). The black in the center represents where labels overlap, or where identity is unknown. They also made a flag with the infinity symbol to represent neurodivergence. They noted the flag's color palette is space-like, which is also seen in a lot of nebula- labels.
History
Neurohoarder was coined on March 13th, 2021, by tumblr user kindness-flags, with both flags being created at the same time.[1]
