The Rock engages in a Twitter battle with Grayson Waller

From the luxurious sets of Hollywood, the established showstopper, The Rock, has once again raised his famous eyebrow to the place which he calls his home. Johnson, recently engaged in a social media warfare with WWE SmackDown superstar Grayson Waller. The back-and-forth started after Waller posted a video on Twitter, in which he daringly claimed that his SmackDown debut at Madison Square Garden was better than what The Rock had. The video post came to the notice of The People's Champ, who delivered a retort on it in his typical suave. 

Grayson Waller followed it up with a proposal to The Rock to enter the "Grayson Waller Effect". It is a segment on SmackDown, that Waller hosts and each week brings a new guest in it. Probably someday down the road, The Rock may drop by and look to give Waller a Rock Bottom.

Following a skirmish with Cena, Waller made his in-ring debut against the Rated R superstar Edge. While it was a lost cause but he put in a commendable effort to demonstrate that he is a bright contender to become the main event superstar in the future.
