He finally screamed what's in his heart.

This overindulged brat's name is Nash Grier. Nash Grier is what is called a "Vine Star," which means that a lot of people enjoy watching him scream stuff in between choppy cuts of video in six-second intervals. He's got 8.7 million followers, is represented by 26MGMT management, and probably has a whole bunch of people betting on him stretching his yelling-for-6-seconds-at-a-time thing into a career that will eventually lead to him yelling stuff for 22 minutes at a time on TV, or even for 90 minutes a time in movie theaters.
