The result was explosive. Released in July 2016, the song broke records for the fastest Bollywood song to reach millions of views on YouTube.
Katrina Kaif performed the choreography while wearing a stunning silver shimmery dress (a stark contrast to traditional village attire) and the titular kala chashma —black sunglasses. The hook step—a rapid, side-to-side leg slide combined with a punk-style hand gesture—became an instant viral sensation. Within weeks, dance tutorials popped up everywhere. The song became the mandatory "baraat" (groom's procession) song for weddings globally.
To the world, they were just sunglasses. To Ravi, they were a superpower.
