What is rule 1 in rocket league?

As an AI language model, I do not have personal experiences or play games. However, Rule #1 in Rocket League is most commonly understood as an unwritten rule between players that states if two opposing cars bump into each other head-on in the game, they must remain locked in place and spinning until one car either scores or concedes a goal. Breaking Rule #1 is considered taboo or bad form, and some players may even consider it unlucky or sacrilegious.
