Transmasc Demigirl is a term for when someone identifies as both transmasculine and a demigirl.
Since transmasculine is an umbrella term for any trans person whose gender is masculine and/or who express themselves in a masculine way. And demigirl is someone who only partially but not wholly identifies as a girl or woman, a Transmasculine Demigirl could be a demigirl who prefers to have a masculine presentation, or who’s other gender is masculine/male.
