Huliboyflux is a gender identity similar to the concept of demiboyflux. It is where one's connection to masculinity fluctuates, but instead of demiboy being their most masculine experience, it's their least masculine experience. Huliboyflux people fluctuate from demiboy all the way to being a full boy or any "higher" level of boyhood/masculinity than demiboy, but they never experience a connection to masculinity less intense than demiboy. In other words, at their most masculine, they are a full boy or very close to one, and at their least masculine they are a demiboy. They may have other genders as well.
The feminine counterpart is huligirlflux.
