History
The term Dionysian to refer to gender along with a flag was coined at some point before January 31 2020 by Tumblr user genderpotion, though the original coining cannot be found. It was then recoined, seemingly unintentionally, by Tumblr user sanctumangelus with a second flag on June 22 2020. Both definitions were virtually identical.

A similar term, Dionygender/the Dionysian Gender System was coined by Tumblr user koraki-pharmakis on June 18 2021 to describe various genders tied to Dionysos.
