You ever get sh** pains, where you've got like one solid chunk of turd. Behind it somethings gone wrong, and it's basically all liquid, and it just doesn't have the pushing power to really move the turd chunk. So instead of pooping, it just builds ups pressure until it starts to hurt. So eventually you manage, through whatever struggle it takes place in, to get that solid turd chunk out, and all that liquid behind it basically just all sprays out at once, like you've popped a cork on a bottle of champagne. And when it's over, it feels like you guts have shifted.
That's called the cork sh**s. And I'm pretty sure that's how Hoppin was born.
