gender-archival:

Mascinfernal was coined by Tumblr user sapphire-crimson-claw-archive on January 31, 2018.

Mascinfernal is described as “a hellgender individual with a connection to masculinity. It is not female-aligned, woman, etc, just linked. Can be both powerful and submissive, sexually charged.”

There wasn’t a flag in the original coining post.
