You'd have thought everyone knew that the one man you don't cross is Dwayne 'The Rock' Johnson, the tankin' professional wrestler-turned actor.
But it turns out one guy - James - didn't get the memo, firing out a negative tweet about the new Jumanji film in which Johnson stars.
WATCH THE OFFICIAL JUMANJI HERE:
James' original tweet said: "I went to see the new Jumanji. FUCK THE NEW JUMANJI. Here's a spoiler. There is no way a character in a video game would lose a life, then be respawned still in possession of the item required to win. That's some bullshit. What say you @TheRock? Otherwise it was quite good."
The Rock replied: "Actually my friend, in the JUMANJI Lore Handbook, it clearly states in article 72 of section 7, that 'any character who loses a life, shall return to their original state with any item they possessed at the time of their demise'. So kindly go f*ck yourself James."
James seems to have taken it all in his stride as bantz, retweeting The Rock's reply with the caption of 'The Rock is the greatest human', later also adding in a comment: 'Dude. I haven't loved you this much since Wrestlemania 18'.
The Rock clearly wasn't really too wound up, either, replying: "I mean thankfully we always have the trusted Jumanji handbook for the rules lol."
Imagine sharing a 'lol' moment online with The Rock. He's pissing himself about a moment you're sharing. Just imagine.
At the end of the day, getting a message of any nature from someone as big as The Rock is pretty bloody cool.
Plus, it's not the first time someone's tried to tango with the actor and ended up getting burned.
The People's Champion once took to the social media site to congratulate Kurt Angle on his return to the WWE, saying: "Congrats to my good bud Kurt Angle and his return tonight to a WWE ring. Special athlete and great human being. Have FUN brotha."
Twitter user Ben Pobjie messaged the former WWE favourite: "Dwayne, wrestling isn't real. It's time you knew."
Then The Rock fought back with something as sharp as the people's elbow, saying: "I like the dry wit. Correct, I do in fact know wrestling isn't real. That's why I said 'have fun'. I also know, you can go fuck yourself."
Moral of the story? Try slamming The Rock and he'll simply tell you to 'go fuck yourself'.
