This one’s very similar to the
deja tú structure (check it out if you haven’t already!).
And, in my humble opinion, it’s another absolute gem 💎
It just means:
👉
Forget + noun
👉
Never mind + noun
So yeah, it’s used to dismiss one topic and shift the focus to something more important.
The crux.
El meollo.
I think you probably get the gist! 😉
