Lafangey Parindey is.. quite a strange name. Reason being 'Lafanga' is a word completely from the Desi Language while 'Parinde' is a pure Urdu word. Also, Parinde was a much respected movie and hence adding Lafange to it seems odd.
Anyway, Lafangey Parindey would literally mean 'Rogue Birds' as Lafanga is used for someone who roams around uselessly on roads and a parinda is simply a bird.
We still have to see how the cutie boy Neil Nitin Mukesh fits in the role of a Lafangaa Parindaa.
