A demigirl (also called a demiwoman, demilady or a demifemale person) is a gender identity describing someone who partially, but not fully, identifies as a woman or girl, whatever their assigned gender at birth. They may or may not identify as another gender in addition to feeling partially a girl or woman.
Demigirl can be used to describe someone assigned female at birth who feels barely connected or disconnected to that identification, but usually does not experience a significant enough dissociation to create real physical discomfort or dysphoria. Demigirl can also describe someone assigned male at birth who is transfeminine but not wholly binary-identified, so that they feel more strongly associated with "female" than "male," socially or physically, but not strongly enough to want to identify as a woman. Demigirls may also identify as demigender, non-binary and/or transgender.
The white represents gender neutrality or a questioning and shifting of gender. The pink represents the traditional color used for femininity, which is associated with womanhood. The shades of grey indicate the partial nature of the gender.
