This is indeed pulled out of the ass. The origin of the word ‘yeet’ is meme from vine. It did get added to several big boy dictionaries. There is speculation that the word was used regionally in the 2000s.

Now a bunch of people think it has some latin origin because it sounds convincing while a quick google search (or AI because, 2023) debunks the claim.

It is a fun word though, i enjoy using it. :3
