Entrogender

Entrogender is a xenogender that describes a person whose gender is slowly, but constantly, wearing away. It can also be used as a prefix for other genders (eg. entrogirl).

History
The term was coined by Tumblr user gyey around 2015.

Flag
The flags were created by DeviantArt user Pride-Flags on September 4, 2015. The gendered color fades to gray to represent the “fading away” of this gender.

Etymology
Entrogender is derived from the word “entropy”.
