Surya Ast Punjabi Mast Meaning

A few months ago a party song 'Sooraj Ast te Baabbe Mast' was there on TVs, from a film called 'What the Fish' and I thought it was a fun line. Now the same sentence gets Punjab-ized and comes up as Surya ast, Punjabi mast.

Anyway, the sense of the line is that as the sun sets, that is as soon as it's evening, Punjabis get 'mast', which generally means they enjoy, but here it is also a euphemism for 'get drunk.' Of course, if we are generalizing so much, we can also say that most Punjabis do enjoy when they get drunk, though I wouldn't suggest that they enjoy only when they drink or just by that means.
