Someone else may have to fill in the gaps for me (or completely correct me if I'm wrong on this).....
But didn't "Yeet" originate when Sami was initially trying to fit in with The Bloodline on Smackdown, while coming off extremely awkward by attempting to use cool lingo? I'm remembering Sami blurting out "Yeet!!" during a Bloodline segment.....so I'm gonna guess Jey, while still a heel, previously used that term at some point?
If so, there is at least some storyline continuity aspect to it....instead of just some word they randomly told him to use after turning babyface, all because it was popular among 12 year old boys in like 2019....
