Post Malone How to Be a Rockstar ... Multiple Attempts Required

Post Malone quickly realized technique is everything if you wanna be a guitar-smashing rock star -- but he was still able to live up to his own song title. Eventually.

Post was doing a show Tuesday night in Fort Lauderdale, when he had Postmates deliver a sweet red guitar from a local Guitar Center. We're told it cost him about $1,000.

help @Postmates I wanna order 100 guitars to smash on tour but it's only letting me order 10!

He originally asked for 100 guitars, with the idea of smashing 'em onstage while performing his new #1 hit with 21 Savage, "Rockstar." Fortunately, he stuck with just one ... 'cause it was a bitch to break.

For those about to rock, Post salutes you! Slowly.
