Here it is. Basically, when one plays the Old Man Game, one's objective is to use as many words that are no longer popular vernacular but would be found in an old man's vocabulary. This is not to be confused with the Dirty old man game. That's something completely different. The persons present when statements are entered into competition are responsible to judge if the word or phrase counts. You can keep score or not, it's up to your group of friends. This is an open source guideline. Any improvement to rules of play are welcome. Good luck and have fun.
