maybe with a dudu on her arm?

Acting or looking like Lady Muck.   Pretending to be of a higher social standing than she is.  Also swanning around can have a similar reference.

On people who are not so bright, Not the sharpest knife in the drawer.

Getting things wrong: Throwing the baby out this the bath water.  Making a pig´s ear of it. 

Getting agitated: In a right two and eight!  Getting your knickers in a twist. 

Throwing the baby out WITH the bath water.

The term "nallari dikmek" is not one you would normally use, if you are describing your own father´s demise.

It carries a high degree of disrespect for the deceased...and is very impolite, if used with reference to human being who has passed away..

You´re quite right AlphaF - we would not say ´kick the bucket´ if we were being respectful and serious. Only if the death was being taken very lightly - or if we were talking maybe about ourselves , eg If I haven´t kicked the bucket before then.

I have another, similar one, but it´s a tad rude.  "All fur coat and no knickers."  

I have a book (somewhere) and it details the history behind idioms.  Some go back hundreds of years.  One theory about the above idiom is that it refers to someone who has committed suicide by hanging themselves - They would stand on a bucket and kick it from under theselves at the final moment. Gruesome

I used to work in the banking industry and I always remember my boss referring to people who were in a bad way financially as being in "Dickie´s meadow" i.e. big trouble (doesn´t have to be restricted to financial trouble).

From time to time my dear mother uses this idiom :  "All my eye and Peggy Martin"

I´ve looked it up here.
