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.

A gender in which you feel mostly masculine but not wholly so nearly like trans but not quite demiboys usually feel more a boy then a girl so most days you feel boy and less days you feel like a girl
"I feel like I'm more of a boy on days and I rarely feel a girl I must be demiboy "
