I think you know by now where to find this definition.
This term's origin is actually from Native American culture, and they used it to describe a person who identifies as a woman and a man, simultaneously. It's basically the opposite of agender; and it's known to be called a third/other gender. You know the drill; I've put some examples below.
"I don't feel like just a woman or a man. If I identified with just one, I'd by denying half of myself. I'm both."
"I classify as androgynous because I express my gender identity with both masculinity and femininity."
