There was a whole load of teardrops on one of Taylor Swift’s old guitars — after a man bought her prized instrument at auction … only to immediately smash it to smithereens!

The footage is going absolutely viral, showing a white-haired dude grabbing a hammer and going full demolition mode on the autographed guitar — after dropping $4,000 on the instrument.

You can hear him giggling like a kid in a candy store, totally relishing the chaos. At one point, it looked like he was about to raise the guitar over his head to smash it to the ground … before the host snapped him back to reality.

The video started blowing up Monday — the scene appears to be from an event called the Ellis County WildGame Dinner held outside Dallas, Texas Sunday night.

People are speculating it might be tied to politics — especially since Taylor recently endorsed Kamala Harris for president.

The man’s antics have sparked a major debate online … with some cheering him on and others saying he could’ve spent that cash in way better ways.
