A mix between aboy and quoigender. It's a gender that feels genderless and masculine in some way but one is unsure to which extent it is masculine and if it is masculine at all.
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 just agender or agender masculine.
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.
