When you wipe your butt on someone's underwear and then you stick the underwear in your mouth and suck it until it's clean. Must be pearly white underwear or the Angry Chester isn't complete regardless of the starting color or quality of the underwear.
I got an Angry Chester last night and now my underwear is cleaner than ever before. Reminds me, don't share drinking glasses with Mike.
