Why all Indians say "bro" SOLVED

I have actually googled this a bunch over the last 3 or 4 years and I finally found an answer that make sense. I am big into Clash of Clans, Clash Royale, and we have a lot of malay, indos in our clan but it seems like the Indians, like people actually from India I'm sure they are young, that come and go you can always identify by their immediate and over use of the word bro.
And since I'm a white dude from south east USA, I always hear it as "sup bro, donate me a drag bro, u gotz that drag, bro? s'all good it u don't bro. BTW yr mom is hot, bro.
