Guns N' Roses did some hardcore hatin' on Donald Trump during a concert -- but they had to figure the audience would love it ... since the show was in Mexico City.

The band paused the music Wednesday night to bring fans onstage to smash a Trump piñata, and they totally went off ... showing no mercy.

YG did the same thing earlier this this week, but with a skinnier piñata -- though we doubt that's gonna make the Prez-elect feel any better.
