As I kid I remember it meaning you smoked a lot of crack, but I'm pretty sure now it means the same thing as "cool as hell"? Am I using it right?
I figured out "yeet" recently by playing Among Us with my kids, so that's cool. But I also don't know what "vibe check" means. I've had people explain it to me in detail and I still don't get it. That one might be unknowable.
It's funny because just like every other thing it was appropriated from Black culture by racist YTs (and now if you want being reappropriated by every other political direction)
