its not moong its muh.....the idiom is ye muh aur masoor ki daal..it means that you are demanding much more than you deserve....sentence is...tum ho to daswi pass par tum maang to doctor banne ki kar rahe ho ye to yahi baat ho gayi ye muh aur masur ki daal..!
Masoor ki daal is red lentil . It used to be prepared as a rich delicacy in royal households, a meal to the taste of the kings. ...Royal Food for A Royal person, so when someone is demanding way more than what he/ she actually deserves this idiom is used :)
