A demiguy (also called a demiboy, demiman or demimale person) is a gender identity describing someone who partially, but not wholly, identifies as a man, boy or otherwise masculine, whatever their assigned gender at birth. They may or may not identify as another gender in addition to feeling partially a boy or man.
Demiguy can be used to describe someone assigned male at birth who feels barely connected or disconnected to that identification, but does not experience a significant enough dissociation to create real physical discomfort or dysphoria. Demiguy can also describe someone assigned female at birth who is transmasculine but not wholly binary-identified, so that they feel more strongly associated with “male” than “female,” socially or physically, but not strongly enough to want to identify as as a man.Demiguys may also identify as demigender, non-binary and/or transgender. The original coiner of the phrases demigirl and demiguy is unknown.
