A person assigned any gender at birth who partially identifies as male. Feeling male is usually more predominant than other genders.

An example is a person who identifies as mostly male but also feels agender.

Falls under the transgender and particularly the nonbinary spectrum. Someone who identifies as part male, part something else. The something else is undefined in the umbrella term, but could be many different genders.
From the Gender Wiki:
Demiboy can be used to describe someone assigned male at birth who feels but the barest association with that identification, though not a significant enough dissociation to create real physical discomfort or dysphoria, or someone assigned female at birth who is trans masculine but not wholly binary-identified, so that they feel more strongly associated with “male” than “female,” socially or physically, but not strongly enough to justify an absolute self-identification as “man".
I was born female, but I feel partially like a boy, but I also feel partially genderless (or agender), too. That means I'm a demiboy.

I was born a boy and identify partially as a boy, but I also feel like I identify as another gender.

Also called "demimale" or "demiguy", someone who identifies as partially male and partially something else (most commonly male/non-binary or male/agender). They may also use he/they, they/he, or just he/him. Anybody can be a demiboy regardless of their biological sex, as it falls under the non-binary umbrella.
"Did you hear Jake identifies as a demiboy? They're trying they/he pronouns."

people who call themselves, or identify as a man, but not entirely, would be considered a demiboy.

demiboy's might also use the terms trans man, masc presenting nonbinary people, or just man. they would use the pronouns they/them, and he/him. the opposite of this would be a demigirl
Aaron wants to be called a demiboy now. their pronouns are they/he. he seems to be happy with this label
