It's typical for Shanghainese, the reflect of people, the word they use, the status of their lives...everything
Just very funny when you see someone just like you and your own friends, and what they're experiencing is just what you will do. You see this movie with friends and just cant stop laughing all the time, and you or your friend get the point at the same time...
Cant stop talking about the movie, it's not only a movie, it's a topic or just a phonomenom you keep talking talking talking until every friend have seen it and have talked about it(you know what, not only friends, elder women and men like it very much, also brothers and sisters...) ya.
