Viritrum was coined by Tumblr user the-gender-collector-emself on March 28, 2020.
Viritrum is described as “This one comes from ‘vir’ (the Latin masculine noun) and ‘neutrum’, meaning neutral. It’s a personal term because while I have been calling myself a demiboy, I never knew what that other part of the identity was. I only just discovered I may be part male, part gender neutral.”
There wasn’t a flag in the original coining post.
