Let's try something new and improved. Here we have a cookie which I am starting off with. Yes, it is chocolate chip. And no it is not real. It may be a tantalising 128 bit, but don't eat it!
Now, the goal is to steal the cookie from the previous poster. In order to this, you have to come up with a distraction for the previous poster, that would make them lose possession of the cookie, and that you can claim it for yourself.
Example: "I set off fireworks in your garage. It's my cookie now!"
"I give you a mock treasure map in search of the Potato of Dignity. My cookie"
I hope that you have the idea now. Please, no scenarios where the cookie gets eaten or damaged. That would just be stupid and contradict the whole idea of this game.
So come and get it! Let's see how long this goes for.
