I assume "orale pues" means "alright then". Does anyone have any other thoughts on what this phrase means?
Órale pues may mean:
OK, See you, Let's start on it or, as you have correctly interpreted, "Alright then".
It depends on context. It is a very Mexican slang (street's or informal language)
I think you have this correct - kind of a way of ending a conversation...especially if it's one you're not too interested in.
There is so much slang in the living language that you will never learn in school or on this or any other website. To truly live in a foreign country you need to learn the slang and the idiomatic expressions as much of the spoken language consists of these. It is like a person from the USA (avoiding saying American) goes to England and hears someone order banger and soldiers or some such thing. You haven't got a clue what it is. Órale pues is extremely common in Mexico and a lot of slang crosses the class barriers.
