The others answered the question, but I wanted to add that this is "new English" to me as well (also non native though). I first saw it in chats with mostly teenagers in ~2021, where I've also learned "let's go" isn't about going anywhere at all (it means the same as w)
This is the first sign we're getting old :) new language features feel new. The language features I picked up in school, that my parents remarked upon, were simply normal to me, not new at all. I notice it pretty strongly nowadays with my grandma, where I keep picking up new terms in Dutch (mainly loan words) but she isn't exposed to them and so I struggle to find what words she knows. Not just new/updated concepts like VR, gender-neutral pronouns, or a new word for messages that are specifically in an online chat, but also old concepts like bias. It's always been there but I'd have no idea what she'd use to describe that concept
