A mix between agender boy and quoigender. It's a gender that feels like it isn't there and masculine in some way but one is unsure to which extent it is masculine and to which extent it is agender.
This might be because they don't entirely understand the concept of gender, because they're neurodivergent, gender apathetic, are confused, are gender non-conforming, dysphoriaflux, etc.
They can't tell whether they're agender or a boy, fluid between being a boy and agender, flux between being a boy and agender, a agender person who dresses and/or acts very masculinely, a agender person who prefers to be perceived as a boy, a boy who dresses and/or acts very neutraly, etc.
They might identify with terms between agender and boy, such as bxy, demiboy, agender masculine, agenderfaun, agenderflux boy, xoy, etc. They might also refers to themselves as a binary man or a agender person despite the fact that they're not sure what their gender identity exactly is.
