Chinese languages

Someone told me "se pei" is a Shanghainese slang for "tough female".

Can someone please help me out with Shanghainese (Wu) slang?

Is this what happens when a person or a country becomes suddenly rich? The Chinese government suddenly have some dough cause of slave-labor factories, and it's now feeling invincible and crazy. Maybe it'll soon be destitute like so many lottery winners. Smile
