Ace filmmaker Karan Johar took a dig at a troll on Thursday, asking him to bring a "bahu" to his home for his mother’s timepass. Taking to Instagram, Karan wrote on his stories, "Firstly, no "bahu" should be a time pass for anyone’s mother. A bahu is a label that comes with ridiculous regressive baggage. She is an individual in her own right and can pass her time however she likes personally and professionally."
