Upon release, the hashtag #kolaveri topped the Indian trends in Twitter on the evening of 21 November 2011 and was trended for three consecutive days. Within a week of the official release of the video, it received more than 3.5 million views on YouTube, more than 1 million shares on Facebook, while trending in India on Twitter the whole time. The song is also a hit among non-Tamils, apparently due to the Tanglish lyrics. Soon after its release, the song was played on US radio station KZYX FM by Mister X, on his show, Music Out of Bounds. By 30 November 2011, it had more than 10.5 million YouTube views. By the start of 2012, it had crossed 30 million YouTube views. The song and versions of it account for more than 200 million of YouTube's total views. The song became the top downloaded song on mobile with 4,100,000 downloads within the first 18 days of release. On 24 November 2011, this song became the first Tamil film song to premier on MTV India. The video was shared by 1.4 million people, liked by 1.8 million people and received more than 1.1 million comments. As of November 2020, the song has 235 million views on YouTube, becoming the second most viewed Tamil song on YouTube only bested by "Rowdy Baby" from Maari 2, another Dhanush-starrer.
"Why This Kolaveri Di" popularised the soup-song genre, which resulted in many filmmakers and actors having such sequences and songs in their films. This resulted in severe criticism with many cinephiles and critics time and again, due to this culture. In December 2015, Anirudh worked with Silambarasan for the "Beep Song". Following the song leak, both of them were criticised widely from several women organisations, including Maadhar Sangam, as the song featured lyrics that found to be explicit and derogative against women. A police complaint was filed against Simbu and Anirudh by the All India Democratic Women's Association from the Coimbatore wing, taking offence over the objectionable and sexist lyrics. Anirudh however denied its connection with the song. 2b1af7f3a8
