New pronoun for us, fellow #trans #nonbinary people. You could be speleothey/speleothem.
If you, like me, are annoyed by typing stalactite and stalagmite (and the rarer stalagnate [a pillar]) every time you have a cave scene, you might be interested to know that there is a word that means all three (and more).
Unfortunately, that word is SPELEOTHEM.

I always knew in theory that a speleothem is a sedimentary rock, but I've never seen a cross-bedded stalactite before 😂

Somewhat silly suggestion, but what if you could mix & match different Speleothem? (aka spikes)
They actually line up pretty perfectly, and although they don't necessarily mesh super well, I think there'd be some use cases.
(particularly tipping dripstone with sulfur)

This is a "dirty" speleothem: essentially a laminated siltstone, ~cemented with calcite. It probably grew close to a fair-sized cave entrance, allowing dust-sized particles (mineral and biological) to become entrained (Wilgarup Cave, Western Australia). Contains ca. 2000 pollen/gram calcite 🧪

Which I can't use, because barely anyone knows what it means (including me, 30 mins ago). I especially can't put it in the mouth of a regular person.
You can, however, make a joke about a stalactite's pronouns being speleothey/speleothem.
But no-one will get it. 😕
