Kiké Hernandez‘s viral postgame interview of the team’s “Don’t give a f***” mindset took Dodger Nation by storm … but the star utility player said it wasn’t a spur of the moment comment — ’cause that was L.A.’s motto throughout their World Series run!

TMZ Sports caught up with the newly crowned World Series champ as he worked an honorary shift at Raising Canes … and he explained how the clubhouse didn’t let any outside talk affect how they went about their business.

“We were gonna do whatever it took to win a game, to win a series,” he said. “I think it showed throughout the whole postseason that we didn’t really care about what anybody thought about us. We didn’t really care about the outside noise.”
