The Rock Cosigns Travis Kelce's Postgame Speech, 'My Boy Said What He Said'

Dwayne "The Rock" Johnson gave Travis Kelce a ringing endorsement ... after the NFL superstar ripped the Cincinnati mayor, calling him a "jabroni" following the Chiefs' victory over the Bengals in the AFC Championship Game!

Of course, Kansas City's 6x Pro Bowl tight end channeled The Rock during his on-field postgame interview, telling Cincinnati mayor Aftab Pureval -- who trolled the Chiefs and their QB Patrick Mahomes before the game -- to "Know your role and shut your mouth, you jabroni!"

Well, the WWE legend and A-list movie star clearly got a kick out of Kelce's clap back, going to Twitter Monday night to show his appreciation for Travis.

"My boy said what he said," The Rock wrote. "I appreciate the venomous 'shut yo' over formal 'shut your' 🤣👊🏽🏆."

Kelce's speech was brilliant ... and anyone familiar with The Rock's signature punchlines knows not everyone can pull off the impersonation!

When The Rock was a WWF/WWE Superstar, he routinely made fans laugh by calling fellow wrestlers "jabroni's" and telling opponents ... "it doesn't matter what your name is!" He'd also threaten to take them to the "Smackdown Hotel." 😅

Kelce earned the right to trash talk after his performance Sunday ... he had 7 receptions for 78 yards and a touchdown, making big plays for his team, as has become routine for the league's best pass-catching TE.

Now, the 33-year-old tight end will face off against his brother, Eagles star Jason Kelce, at Super Bowl LVII in Arizona ... a.k.a. the "Kelce Bowl", a.k.a. the "Andy Reid Bowl."
