What exactly is 'Brinicle'?

Well, there's not much information on it yet - except that 30 of Korea's top celebrities are shouting it through a mysterious video clip. It's probably the one place that the top three MCs of Korea - namely Yoo Jae Suk, Shin Dong Yup, and Kang Ho Dong - appear together, minus the end of the year shows.

But it's not just the three MCs shouting its name. The cast of Korea's top variety shows 'Infinity Challenge', 'Running Man' and '1 Night 2 Days' also came to endorse 'Brinicle'. There are also some famous actors, comedians, and singers like Boom, Yoon Jong Shin, and Kim Hee Sun.

Check out the video below (and see if you can spot the celebrity who says 'broccoli' instead!). Do you have any guesses as to what this may be for?
