BTW I like one of Sindhi Muhawra. You might have heard that..
**
'Paana main Chandia Magsi' - Like Chandia and Magsi**
Our Ammi used to say this when we siblings and cousins used to fight. The Muhawara came into being due to traditional enmity between Chandia and Magsi tribes
I think 'yeh munh aur masoor ki daal' is used when someone becoming more demanding than his/her abilities / status or asks for something he / she doesn't deserve.
