Respectful term for nonbinary people and people of unknown gender?

Whoa, hey, I'm just an innocent bystander here. I knew this username was a mistake.

Hey! Don't look at me, I like Comrade. I support Tovarich even! But some people think it's a little too Red! Talk to Scarlet...oh. Oh....OH!

Seriously though, let's not make 'boss' the go-to gender neutral term. Always weirds me out when people I know refer to me as 'boss', makes me feel like some kind of mid-level mobster.

We don't know you're not. Boss.
