Cassgenderless

Cassgenderless or cassagender is when one's gender is so unimportant that they can't tell if they even have a gender at all. Not caring about one's gender to the point where it might as well not exist.

History and flag
The term and flag were coined by Tumblr user solidwater05 on September 19, 2022.

The flag consists of 7 horizontal stripes. From top to bottom, the colors are dark grey, pale blue, pastel green, muted green, pastel green, pale blue, and dark grey.

The colors have no confirmed meaning, but the flag as a whole was created combining the cassgender and agender flags.
