The followings are the definitions …to some extent… 
Paindoo is someone really MASOOOM
Paindoo is a very distinctive term used to describe saday jai log
Paindoo is not about physical attributes, but about “state of mind”. A true Paindoo (like myself and Chann) are not pretentious self absorbed copycats. A true Paindoo never lets tradition go die so easily; they smoke Folks-Own or Embassy even when they can afford Goldleaf. They drink their tea in soccer, even at the high society places, such as big hotels and palaces. They don’t give a kcuf about what Shahri people think of them. They are very content with their way of doing things and love their heritage. They don’t speak English like some wanabe Kathay Angraiz who say “Yes Sahib” to every thing.
The bottomline is if you ain’t Paindoo, then you have some big problems.
paindu is just a labelling of a person who acts awkward intentionally or unintentionally while having his backgound as belonging to modernised society(urbanised).
like if you wear sharp bright colors e.g ppl call paindu. It has nothing to do with mental intelligence, as you know that educated ppl can be paindu in terms of thier ideas.
