Neurofluid is when one identifies with more than one neurogender, and is fluid between them.
History
Neurofluid was coined by Tumblr user pupyzu on March 17, 2021. The flag was created by the same user on the same day.[1]
Flag
The neurofluid flag has eight vertical stripes with a black infinity symbol in the center.
The alternate flag was created by Tumblr user synpa-tee on June 6, 2021.[2] It has seven horizontal stripes: two blue stripes, two pink stripes, a pastel red stripe, a blue stripe, and a purple stripe. The three center stripes come from the neurogender flag, but they have been lightened. The outer stripes come from the genderfluid flag. There's also a black infinity symbol in the center.
