Greygender

Graygender or greygender is defined as: "a person who identifies as (at least partially) outside the gender binary and has a strong natural ambivalence about their gender identity or gender expression. They feel they have a gender(s), as well as a natural inclination or desire to express it, but it’s weak and/or somewhat indeterminate/indefinable, or they don’t feel it most of the time, or they’re just not that invested in it. They’re not entirely without a gender or gender expression, but they’re not entirely “with” it either."

The term was coined by invernom in March 2014.
