In Veneto (Italian region) we put this
verb in a large amount of sentences, with different meanings and syntax.
It usually refers to
something you managed to accomplish, but it can be used to indicate
something you found or, generally, to the ability of someone to be an efficient person.

(Ehi guys, I succeded in getting the notes for the exam.)
Ma ti reffi?
(Can you do it?)
Non mi reffo un cazzo.
(I don't understand/I'm not able to do it.)
Reffarsi la mattina è sempre un problema.
(To be lucid in the morning is
always a problem.)
