A mix between agirl and quoigender. It's a gender that feels genderless and feminine in some way but one is unsure to which extent it is feminine and if it is feminine 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 feminine.
They might identify with terms between agender and girl, such as gxrl, demigirl, agender feminine, agenderfae, agenderflux girl, xirl, etc. They might also refers to themselves as a binary woman or a agender person despite the fact that they're not sure what their gender identity exactly is.
