So it's not Hindi, right? It's some regional language.
Thank you so much. This absolutely makes sense in the show context 😃😃
Bauranta doesn't seem to be for me but I can't be sure. It may be regional to Bundelkhand (where Sanju is from). Maybe it's a derivative of the word/phrase "Baura jaana" which translates to going crazy.
Glad it helped!
