This is the pizza beer koozie made by Youtuber the Vulgar Chef (aka Kyle aka Fangtooth aka the exact kind of person you'd expect to bake a pizza beer koozie). He includes video instructions for how to make your own. Interesting, but who wants a koozie that warms your beer and cools your pizza? Nobody wants a hot beer or a cold pizza. I'm lying, I want both of those things all the time. I could eat a whole uncooked frozen pizza and wash it down with a beer that's been rolling around in the back of somebody's trunk on the hottest day of August. That's just the kind of person I am. "Disgusting." Okay well I was going to say superhero but I guess it takes one to know one.
Keep going for the video.
Thanks to Stephanie B, who agrees a koozie made out of Chex-Mix is far more practical.
