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.
