It was him and Deckard Shaw breaking out of prison. That was a real "bro" moment.

I would say him breaking the vending machine in Furious 6 his maori dance at his daughters soccer game and his big return at the end of Furious 7.

"Took longer than I expected"

For me it would be from Fast Five, when he confronted Dom face to face in Brazil and Dom said "This is Brazil!". The Rock's intense stare was everything in that scene.
