Orbgender

Orbgender or spheregender is a gender that feels completely round. It feels like it has no edges but instead is constantly round and smooth, like an orb or a ball. It is not sharp, rough, or cornered.

History and Flag
The first known use of orbgender is in the posts by DeviantArt user Pride-Flags when they created both orbgender flags on September 3, 2015.
