Pinch, poke, you owe me a coke.
Have you ever heard that phrase? It’s a silly thing some kids say (and some adults too), when two people say the exact same thing at the same time.
For example:
Person A and person B both say at the same time: “Glee is my favorite TV show.”
Then, Person A (or B) will quickly say, “Pinch, poke, you owe me a coke.”
Sometimes with kids there might be a little pinching or poking, but nothing serious. And rarely does anyone ever really get a free coke.
