The Rock was recently asked on Twitter, by a fan, about wrestlers breaking kayfabe during promos, to which The Rock responded with:
"Breaking 'kayfabe' is easy, cheap and never entertaining. Boys who are desperate do it all the time."
Cena then chimed in by saying: "People should stick to the difficult stuff like mom jokes, sexuality, and making light of someones appearance."
The Rock then responded with: "The first sign of fear is when a man answers my raw aggression with a nervous smirk."
Cena then posted: "Second sign is when he can no longer speak in public without reading his words. Have a nice night @TheRock."
