Dwayne 'The Rock' Johnson

When Dwayne Johnson put certain unnamed members of his “Fast and Furious 8” cast on blast as “chicken shit” and unprofessional, he tossed out a line that may have confused some. In calling out certain co-stars — by all reports, Vin Diesel — he labeled them “candy asses.”

This is my final week of shooting #FastAndFurious8. There's no other franchise that gets my blood boiling more than this one. An incredible hard working crew. UNIVERSAL has been great partners as well. My female co-stars are always amazing and I love 'em. My male co-stars however are a different story. Some conduct themselves as stand up men and true professionals, while others don't. The ones that don't are too chicken shit to do anything about it anyway. Candy asses. When you watch this movie next April and it seems like I'm not acting in some of these scenes and my blood is legit boiling – you're right. Bottom line is it'll play great for the movie and fits this Hobbs character that's embedded in my DNA extremely well. The producer in me is happy about this part😉. Final week on FAST 8 and I'll finish strong. #IcemanCometh #F8 #ZeroToleranceForCandyAsses

Fans of Johnson, the action movie star, may be a bit confused about what exactly “candy ass” means. After all, it’s not necessarily an insult you hear thrown around in an argument. However, for those who remember Johnson’s other identity — former professional wrestler The Rock — Johnson calling someone “candy ass” is nothing new.

All the way back to the ’90s, The Rock used it as one of his trademark catchphrases on WWE programming, throwing it at anyone who stood in his way. From “laying the smack down on your candy ass” to sticking something “straight up your candy ass,” it was a barb he always had at the ready.

With well over a decade of calling people “candy ass” under his belt, it was only relatively recently that Johnson finally revealed the origin of the insult. During his 2013 run as WWE Champion, The Rock appeared on “Smackdown” to finally reveal the truth behind the phrase.

It goes all the way back to when he was 15 years old and had a standoff with somebody over a candy bar during a visit to Hershey, Pa. “The one thing I wanted was a Hershey’s Whatchamacallit,” he says. The journey for a single piece of candy didn’t sit well with his friends, but finally it paid off.

“Finally I found that Whatchamacallit and right before I grabbed it, someone else steps in and grabbed it before me,” he remembers. “Something historic happened that night because I said something that changed the course of history in the WWE forever.”

So what did he say? “if you don’t put down that candy, I’m gonna’ kick your candy ass,” he claims. And thus, a personal catchphrase was born. Of course, as Johnson later reveals in the segment, the target of his insult was an old lady. But what can you do? Johnson wanted a candy bar and the phrase lived on to help define his entire wrestling career, which led him to Hollywood.

In fact, it’s entirely possible that without “candy ass,” the world would have no idea who Dwayne “The Rock” Johnson is. So really, he should be thankful to that old lady that he probably made up for comedic effect.
