I wasn't quite sure what the chant was about. It didn't sound like 'Gayle, Gayle' or 'Sixer, sixer', which is what fans might ask of the batting team, Royal Challengers Bangalore, ordinarily. But then, they were playing at Wankhede, not Chinnaswamy. So were they screaming for Sachin Tendulkar?
I was watching the match on TV, and all I could make out were the vowels: ee-aah, ee-aah. It was a while before the word formed properly: 'Cheater'. So, 'cheater, cheater' was the chant.
The 'cheater' in question was Virat Kohli. Towards the end of the Mumbai Indians innings, Ambati Rayudu was trying to make his ground at the non-striker's end after being sent back by Kieron Pollard. He hit Vinay Kumar's leg with his bat, and Kohli threw down the stumps with a direct hit. Rayudu was declared run out.
