John Cena Trolling means in slang: John Cena trolling refers to a type of trolling that is used mostly on Twitch and Hitbox streams with a YouTube video player. This troll creates a video that appears innocent for YouTube, then changes to John Cena screaming “JOHN CENA!” After that, a short montage of Cena wrestling is shown. This is a lot like a Rick-roll and was very popularized by BrittanyVenti’s streams. (in Slang Dictionary, added by Boogle)
