Demicisgender
Demicisgender, or simply demicis, is a gender modality in which one identifies partially as their assigned gender at birth, and partially as something else. For example, being an AFAB demigirl and as a result one is partly cisgender. The other part of one's gender can be any gender, including agender, or any other combination of genders.
It should be noted that not all AFAB demigirls and AMAB demiboys (examples) are demicisgender, as some may not be comfortable with the term.
