I couldn’t list all the ones I know, only the ones I have come across. I remember once someone tried making the whole Bee Movie script their pronoun. Another time they were just dolphin sounds. I was like “guys, I have every intention to uphold your validity, but I need to throw a few rules into the equation”. Just basic courtesy stuff.

All the ones I recall coming across that I can replicate:

First person:

I, we, me, myself, drag, shadow the hedgehog, NVIDIA GeForce RTX 2060 Intel Core i5-10400F CPU 16.0 GB RAM

Second person:

You, your, yourself, drag, shadow the hedgehog, NVIDIA GeForce RTX 2060 Intel Core i5-10400F CPU 16.0 GB RAM

Third person:

She, he, it, that, this, xe, zhe, those, they, drag, shadow the hedgehog, NVIDIA GeForce RTX 2060 Intel Core i5-10400F CPU 16.0 GB RAM
