It’s Miami (read: Spanish) for “word” or “cheers”

It means " go" or "let's go"

Sure but what’s it used for. To finish a conversation.

It’s both, it’s not just a Miami thing. I hear it all over Latin America. In both ways like dale dale Olimpia (go <team> go).

Me: I’ll have a burger. Waiter: dale.

I don’t hear it much in Argentina tho, but maybe I wasn’t listening for it.

Don't forget "vale" which I always think of as being Spain Spanish but you hear it all over the Spanish speaking world too. Which is like almost the same, but not the same.

You could translate the Spanish literally as "hit it". It's like saying "alright!"

I think “let’s gooooooo!” Is probably closer? Ish

If we are being literal literal it’s “give it” or “give (it to you)”

Right, but that obviously isn't how it should be translated in context.

It's pretty close. I always think of "send it" as a pretty close English equivalent phrase.
