When a trend, a First-World import in particular, catches on, the first instinct is to jump on the bandwagon with a slew of hashtags, memes, pictures or carefully executed videos. Virality feeds off these tools. And let's admit it, if you manage to quieten the critic in you, visuals of people pouring a bucket of ice over themselves — or more recently, gyrating to Canadian rapper Drake's track, In My Feelings, before a slow-moving car — can be fun. Until of course the fun fizzles out, like it did for three Mumbai lads, who took the Kiki Challenge to the city's lifeline and got caught for attempting stunts on a local train.
