imoga-pride:

Uingender: umbrella term for all genders undecided/unsure, unknown/unnamed, unidentified/undefined/unfixed or unexplainable/undetermined in nature. 

Also a term to refer to a gender that isn’t fully unspecified/unstated, or a gender in which undefinition/unfamiliarity or unknowledge/undetermination is its defining feature. May simply be used as “uin”, ie. “my gender is uin”.

Not the same as gender questioning or ungender.
