General

I like the pattern of sticking to 3-letter acronyms--BDP works for that!

My half-serious suggestion is BBQ: Big Beautiful Queer.

This is all very good. I do hope that NB people jump in because I would hate for non-NB people to come up with something instead of NBs deciding what they want. That would be the suck otherwise.

especially considering BBW and possibly BHM certainly weren't coined by fat women and men (respectively).

Did not know that. Doing me a heckin' educate, my friend.

fat enby here and I've been trying to come up with a term, but at the moment nothing comes to mind. maybe FAT (Fat Agender Titan).

Continuing the theme of food-related acronyms: BLT (big lovable they/them)--though this one isn't great because it implies all enbies/GNC people use they/them pronouns (or pronouns at all).

Can you tell I like alliteration based on the fact that I'm suggesting only things that start with the letter B? But please, any suggestion fron enbies is more than welcome. I like the euphemistic nature of BBW and BHM, but FAT is a fun one!

I'm running into the issue of there not being a good, gender-neutral noun describing people that doesn't have an... academic? clinical? formal? connotation like "human" or "person" have.

EDIT: Another suggestion came to mind that's sadly not food-related nor starting with the letter B, but I like how it rolls off the tongue: TNB (thicc non-binary)
