Mahindra Group's billionaire Chairman Anand Mahindra responded to a man on Twitter who asked him to gift an SUV on his birthday with the definition of the word 'chutzpah'. The word means extreme self-confidence or audacity. "Full marks for chutzpah, Vipul, but unfortunately I can't say yes. Mera dhandha bund ho jayega!" Mahindra tweeted.
