Noun. NB (also Nb, nb, and the phonetic "enby") is an abbreviation for "non-binary" and denotes a spectrum of gender identities that do not follow the traditional gender binary expressions of "male" and "female".

NB is often used attributively to describe people who identify as non-binary and is also often used by those individuals to describe themselves.

**Important: NB is NOT to be confused with NB, which has its own listing; that's right, they're homonyms. Good times.

NB, The gender identity, is rarely expressed with periods, in part to differentiate it from the more commonly punctuated latin abbreviation for 𝘯𝘰𝘵𝘦 𝘣𝘦𝘯𝘦 but also as a matter of visual preference and in keeping with general LGBTQ nomenclature.
Urban Dictionary has not yet responded to my complaint regarding their existing definitions of "NB"; instead, this important category of gender identity and its distinction is being ignored as if it doesn't matter. How very interesting.
