Outhrat or cateline: eligender categories; a catch-all term for experiences beyond a given set of gender categories, and a term for those who feel their gender is beyond categories or when no known category fits; experiencing gender category otherness or otherliness.

The OED's earliest evidence of "otherliness" is from 1937, but here it is in a headline from 1922.  From The Children's Newspaper, April 29, 1922, p. 5.
