Cendgender is an umbrella term for any genderfluid identity that switches between a eugender and its antigender. This could also be used as a prefix, such as cendboy, cendgirl, and cendnonbinary/cendenby.
Cendegender was coined by an unknown through Tumblr user pride-color-schemes on the 26th of July, 2016.
The cendgender flags were coined by Tumblr users pride-color-schemes and pastelmemer on the 26th of July, 2016. The cendgender uses shades from the non-binary flag, while the cendboy and cendgirl use blue shades for masculinity and pink for femininity. The colours fade into their complementary colours to represent their antigenders ("opposite" genders).
