Gendersylph

Gendersylph, also known as Genderfeor, Genderfoan, or Genderfen is a form of genderfluidity in which someone is fluid exclusively (or nearly exclusively) between xenogenders or otherwise uncommon identities. Someone who is gendersylph would never (or very rarely) identify as a gender within the binary. They almost always identifies as something non-binary. This identity can change at random and can also fluctuate in intensity.

History
Gendersylph was coined on May 1 2018 on the Tumblr blog uncommongenders.
