If you are wondering what the #HandcuffChallenge is then head over to Tik Tok and Instagram to watch a plethora of social stars doing this fun challenge. From TV superstars Siddharth Nigam, Avneet Kaur to dancing sensations Melvin Louis, Awez Darbar and social stars Nagma, Mrunall Panchal, Unnati, Anam Darbar and more, everyone is hooked to the challenge on the melodic track "Just you & I".

The best part of the challenge is that one does not have to use handcuffs alone- social stars are seen linking themselves to not only people they love but everyday things like phones, shoes and even a TV set. The basic premise of the challenge is to tie yourself to something or someone you can't live without.
