This video comes with very little context, but here's what we do know: This guy's girlfriend cheated on him; he is very upset about that; he doesn't care who knows it.
Of course, the last point is merely speculation based on the fact that he let a complete stranger capture footage of him smashing up his now-ex-girlfriend's car in broad daylight. Did he think that footage wasn't going to end up online?
Adds the video's original uploader, "If it makes you feel any better she will probably be doing him while you are in jail ...lol."
Quite.
