Non-binary.
Nonbinary mostly means the same thing as “genderqueer” — “An identity vocabulary of only two possibilities is insufficient to explain someone like me” in the case of non-binary, and “queer, instead of normative, gender-wise” in the case of genderqueer.
Edited to Add: In other words, “etcetera”.
Those of us who choose either of those identifiers (yeah, I do, for the benefit of those who aren’t well aware) do not necessarily have an immense amount in common with others who do likewise. I can give you a brief rundown
Subtypes:
agender = not into any gender identity thank you very much
demigirl = I got times when I’m kinda femme and days when I’m more agenderish or neuter-ish
demiboy = same idea except kinda masc
genderfluid = my gender identity shifts… it may mean I have boy days and girl days but it may mean instead that I am demigirl some of the time and agender at other times. Or it may mean that for seven years at a stretch I was a boy-person and for the last three I’ve been more of a girl-person.
bigender = not BIG ENDER but rather Bi-GENDER, two gender identities coexisting somehow
gender invert = not so fluid, this would be male girls and female boys, gender not matching sex
butch = masc but not (necessarily) identifying as man or male
femme = feminine but not (necessarily) identifying as woman or female
