Unlike Bambaiya, Calcutta's Hindustani dialect much less known.

But it has got (maybe for the first time ever) documented thanks to social media + rap culture.

Enjoy this cheeky song (NSFW).

Heavily influenced by Maghi, probably due to colonial migration patterns and given how close Maghi speaking regions are to the city.

Heavy native use of Magadhan-native words and low Farsi use (ironically in some cases less than High Hindi).

In many cases, even classic Hindi-Urdu features like vowel length not present. No inflections for number. No inanimate gender. Basically a LOT of Magadhan features.

Of course since it is very low prestige, educated speakers might be able to code switch with std Khari.
