No south, Buddy- I am ashamed to call you a fellow countryman. Regionalism will get us nowhere. The moment we start thinking in terms of one-india, the better it will be for all of us.
Abusing konkanis, maharashtrians, bhiyas, biharis... is not going to help anyone - it only serves to divide the nation.
I hope you grow up and grow out of your biases real fast
