Blankgirl, also known as blankwoman and blankfemale, refers to a girl who cannot explain their womanhood any further than being a blank space. It is a subset of genderblank.
The fluid counterpart is blankgirlfluid, the masculine counterpart is blankboy, the non-binary counterpart is blanknonbinary, the androgynous counterpart is blankandrogyne, the neutral counterpart is neutrablank, and the xenine counterpart is xenoblank.
Blankgirl was coined by Tumblr user nonbiarrow (Reddit user elhazelenby), April 20th, 2021. The blankgirl flag was created by the same user on the same date.
The flag is the same as the genderblank flag but with a pink field on the top half of the flag, representing womanhood.
