Marfluid, also known as Mascfluid, is a form of genderfluidity where one experiences only or mostly masculine genders. A marfluid person may be fluid between gender such as binary male, demiboy, proxvir, solarian, and any other genders that are masculine. A marfluid person never, or very rarely experiences feminine, androgyne, unaligned genders, or any other genders that are not mostly masculine.
Marfluid was coined of time before August 26, 2014 by the now deactivated Tumblr blog a-tiny-peach.
The flag was designed by kiloueka on pride-color-schemes on July 29, 2016. The blue stripes represent fluctuating masculinity. The three red stripes represent the surface of Mars, making the flag look like a landscape of Mars.
