Accipiogender is a term that encompasses individuals who grew up without the imposition of gender roles (gender-neutral parenting), and who may or may not identify themselves with gender(s) later on. This may be used interchangeably with the UAB label in some cases.
The flag was coined by Tumblr user beyond-mogai-pride-flags on August 4th of 2017. It contains the following colors: black, symbolizing the mourning because of bad things caused by the imposition of gender; blue and pink, representing cisnormative and exorsexist/binarist imposition of gender; white, a neutral color, is layered behind the imposition of gender, and symbolizes the neutral or non-existent experience of gender. The yellow bird means freedom.
The prefix accipio- (pronounced ah-chee-peeoh) is Latin for 'I accept, I take for myself, to recognize, to understand'.
