A dude was not happy about his girlfriend cheating on him, so he did (arguably) a pretty petty thing. The man apparently paid for his girlfriend's hardwood flooring, so he decided she didn't deserve it anymore. He and a friend utilize some heavy duty power tools and destroy the flooring pretty badly. It's a complete mess in her apartment (?) after they're done.
He then films her reaction when she finds out her floor is jacked up. "What is this I came home to? Like, friggin', the whole floor is gone. Like, are you serious. That was so freakin' childish of you. So petty. Like, what's the reason for that? Is that all you can say is 'mmm'? Huh? Is that it? You know, you're so freakin' childish... no wonder I cheated on you. I needed a man."
