Dwayne “The Rock” Johnson and John Cena traded new insults over Twitter on Thursday. The insults began when Rock responded to a follower about “breaking kayfabe” during promos.

The Rock: “Breaking ‘kayfabe’ is easy, cheap and never entertaining. Boys who are desperate do it all the time.”

John Cena: “People should stick to the difficult stuff like mom jokes, sexuality, and making light of someones appearance.”

The Rock: “The first sign of fear is when a man answers my raw aggression with a nervous smirk.”

John Cena: “Second sign is when he can no longer speak in public without reading his words. Have a nice night @TheRock.”
