So much money, it is meaningless. That is a good way to define most billionaires, but how much money do you have when you can throw away $100,000,000 on a wedding? Perhaps you need to be the wealthiest billionaire in India.
Billionaire Mukesh Ambani and his wife threw a wedding for his daughter Isha that is said to have cost 1/10th of a billion dollars. Throw around that kind of money and you know Hillary Clinton and Beyonce and John Kerry and the like will smell the flowing money and come to be close. It was a decadent affair.
The Wedding (Be warned, these are not the beautiful people, they are the gluttonous few.)
Makes sense why it would be referred to as the 'big, fat, Indian wedding'.
