A demiboy (sometimes known as a demiguy, demiman, demimale, or demidude person) is a person who identifies with aspects of masculinity—regardless of their sex assigned at birth.
Tumblr user Transrants designed the demiboy flag in 2015.
The demiboy flag has three colors. Here’s what they are thought to mean:
Blue represents manhood or masculinity.
White represents non-binary or agender identities.
Grey represents the grey areas and partial connections and the possibility of more genders rather than the two on the binary spectrum.
Flags are 3’x5′ polyester.
