Amazingly, it would appear that "tysexual" isn't already a "thing" outside of being a username for a handful of mostly abandoned online accounts. I think it'd be pretty funny if tysexual came to mean an orientation which one didn't wish to constrain or explain by way of strict definitions. For one thing, it'd be funny because it's really about co-opting my personal individualism and expanding that to a collective. Also it'd be funny because it'd be taking a concept defined by the idea that labels aren't necessary, and defining it via label. That's a bit ironic for obvious reasons.
Not that I expect anyone to pick up "tysexual" and run with it. But talking about that version of the universe isn't funny, so why the fuck would I do that?
