Aquoigender is a mix between agender and quoigender. It's a gender that feels like it isn't there, but one is unsure because they don't entirely understand the concept of gender, so they can't tell whether they have a gender because they don't know what gender "feels" like.
An alternate definition to the term is that one is partially genderless/agender, but they can't tell/find what the gendered part of their identity is.
