Basically, one person puts something into the soda machine. It can be whatever.
The next person says what the person before them gets out of the soda machine, and then puts something in.
And it continues like that, so it's like this
Person 1: I put a quarter into the soda machine
Person 2: You get a hotdog. I put in a notebook.
Person 3: Okay, you get world peace. I put in a kite.
It's not usually as boring as that, since that was just an example.
So to start us off, I put Applejack in the soda machine!
