A set of rules that one can choose to use when playing soccer. When playing by Slovenia Rules you may use your hands, grab your opponent, punch your opponent, stab your opponent, and pretty much do anything that is not allowed by the regular set of soccer rules. Also, under Slovenia Rules you may call back a goal that your opponent has made for no reason whatsoever.
Player 1-"Hey that guy just picked up the ball and threw it into the goal"
Player 2-"They must be playing by Slovenia Rules"
Player 2-"No, we're calling it back"
Player 1-"What?!? Why?!?"
Player 2-"Slovenia Rules dude"
