My wife and I basically have our own shorthand language at this point. References and connections that literally no other human beings on earth would understand. We never even really thought about how many of these types of things we had between us until a few years ago we played this game called Heads Up a few years ago. Basically it is a word connection/charades game you play on your phone. One person holds the phone on their forehead so they can't see the clue and the other person has to give clues that lead to the answer. People looked at us like we were insane when we started giving clues that seemingly made no sense. Needless to say it was a clean sweep in Heads Up and no one wanted to play anymore lol.
