A pronoun for a child with no gender identification. Coined by parents that are sensitive of their children being mislabeled a boy or a girl, despite their biological anatomy. By age 4, most children will understand where they are within the gender spectrum, serving this term to render them confused as to why the hell their parents called them a theyby.

Support for this term is driven largely by SJW crowds, the LGBTQ community and virtue-signaling of the Left. Left-leaning ideology emphasizes gender-neutral pronouns and believes humans can identify as any gender at any time based on emotion, rather than physical characteristics.
Co-worker: "When is your child due?"
Janet: "In two weeks!"
Co-worker: "Is it a boy or a girl?"
Janet: "Neither - it's a theyby!"
Co-worker: "A theyby? What is that? Does it have boy or girl parts?"
Janet: "That doesn't matter! They will be whomever they decide to be!"
Co-worker: "....huh?"

"OMG a baby!! Tell me if it has a penis or a vagina so I can know what gender roles to assign it!!!"
"Um, well they're sort of a Theyby... The term 'private parts' exists for a reason, you feel me?"

Hey look, we had a theyby!
A term that shouldn't exist because it's dumb and also the most petty thing that has been said for a while. It's also worse than just saying "baby" because the term baby is already not putting someone in a gender category where saying "theybie" is putting them in the non-gender category
I think that people should calm the fuck down and just stay with baby instead of complicating the world by trying to change it to theybie
