Many people are confused about the meaning of Indian “headshakes” and how to communicate using them. That may explain why a satirical video deciphering different types of Indian headshakes has gone viral.

The 1:44 minute-long video, titled “Indian headshakes, what do they mean?“, has attracted more than 1.2 million views since it was published in YouTube on February 16, 2014. And it has generated interesting reactions on social media platforms such as Reddit and Twitter:

I have always loved the Indian headshake – but now I LOVE it even more. This is brilliant. http://t.co/eHxIyKqJjc

Paul Mathew, the video's writer and director, told the BBC: “If we had known that this video was going to get such awesome viewership we would have shot it better.”
