A George and Jimmy ball is a tennis ball that has two holes cut in it, so that two men can put their penises in it at the same time.
Person 1: Hey guess what I saw Daniel doing!
Person 2: What?
Person 1: He was using his George and Jimmy Ball with his brother and I walked in on it! It was more disgusting then that time i saw you giving that chick a hot carl!
Person 2: Dude, that's not cool.
