ESPN used to run a commercial featuring a young couple having cutesy time on the couch. As unsavory as that image was to a sports fan just wanting to watch game highlights, the visual turned absolutely repugnant once the camera zoomed out to reveal the guy was wearing an Ohio State sweatshirt, while the girl was sporting her Michigan threads.

Just thinking about it makes you uncomfortable, right?

Now imagine a Giants fan and a Dodgers fan embracing on the couch, making out and whispering sweet nothings in each other’s ear. I don’t know about you, but I just threw up a little in my mouth.

Well, that is because the two fanbases don’t get along. In fact, they downright hate each other. They hate each other’s teams, their team colors, their hometowns and their regional vernacular. They even hate the air the other side breathes (with good reason, at least for Giants fans—LA air is filthy).

And it doesn’t help that the players in opposite dugouts hate each other, too, carrying on a rivalry that extends back to the New York days for both franchises.

The list of reasons why the two sides hate each other is seemingly endless, but here we’ll just look at five of the reasons Giants fans hate Dodgers fans so much.
