The word "cool" is a relative term, in that everyone has their own ideas of what exactly constitutes coolness. I once dated a guy who rode a unicycle everywhere and he thought it was the coolest thing on the planet. On any planet, actually.
Obviously it wasn't cool at all, but he thought it was amazing, and I just didn't have the heart to tell him that it was the most ridiculous thing ever. Although I hope someone told him at some point because otherwise it's just too sad to imagine.
My point here is that I've created a list of 20 of the coolest fans in sports. I did my best to be broad with the definition of cool, as an attempt to satisfy all you cool aficionados out there. Which means none of you will be.
But I can live with that, because these are all 20 terrifically cool sports fans. And if you don't agree, perhaps it's because someone involved here isn't cool, but it's not the fans. It's you.
