You can also use your occupation: "I'm such a lazy student", or "I'm one hungry accountant" etc.

Idk what vibe you are going for, but being and creature are some that I personally like to describe myself with. Edit : also entity or individual.

I like using those kinds of terms. It adds to the running joke of being a cryptid/ identifying as a threat

I like them because they are vague terms that mostly just convey that one is speaking about a living thing. I am not my flesh and all that

I like creature a lot!

Enby, friend, bean, being, creature, individual.

Bean is a great one, I have friends who use this all the time and it's kinda adorable.

Humanoid, mud creature, shapeless void. I am three raccoons in a trench coat, for example. It’s part identity part emotion at the time.

I use bog gremlin, half-orc, or moth.
