Bro Vro sodhanai

What is with everyone calling each other bro?To be more accurate : Vro. I remember a time we used to call each other “sir”, “dude” etc, but this Vro thing is going a bit out of control. Today at office the catering captain called me Vro, when I came home the neighbor kids playing outside called me Vro. I’m 30+ years old and this feels konjam weird. Has anyone experience the same? Any other words that are expected to trend next ?
