Xingender (sometimes shortened to xin) is an umbrella term for all genders which are xenine in nature (XIN). It can be used as an umbrella term for any genders that are primarily related to a xenogender. XIN is not synonymous with non-binary, because, for example, neutrois is non-binary but it is neutral in nature, not xenine. It can also be used as a gender on its own, referring to any gender that isn't fully defined by being xenine, but is still related to being xenic, or a gender in which being xenic is its defining feature. It's often used by people who cannot narrow down their gender any more than being a xenogender.
Xingender was coined by Tumblr blog beyond-mogai-pride-flags on June 18, 2018. The flag used the colors of the xenogender flag and the xenic flag.
