Some more terms I've coined! In order:

Peripangender- Identifying with, but not as, pangender. The colors are based off of the perigender flag, but with a white stripe representing all genders, like how white light is a combination of all colors of light.

Periagender- Identifying with, but not as, agender. The colors are based off of the perigender flag, but with a black stripe representing a lack of gender, like how black is the absence of light.

Periapangender- A combination of Peripangender and Periagender.

All of these terms are free to use without credit, and I didn't coin the term Perigender, so feel free to coin terms based off of these without crediting me or even tagging me. :)
