The "Am I Being a Douchebag?" Rule
Players should not be looking to call for a penalty stroke at the drop of a hat for insignificant occurrences. For example, if a guy tees a ball up and touches the ball with his club and it falls off the tee, don’t be a douchebag and tell him that counts as a stroke or that he gets a penalty for re-teeing the ball (FYI, this is actually neither a stroke nor a penalty under the rules). Just laugh at him (or with him) instead.
Before you decide to call your opponent out for a possible rules infraction, or make your own attempt to violate a rule, ask yourself, “If I do this, am I being a douchebag?” If the answer is either "I'm not sure" or “YES,” then re-think things carefully before acting any further. Note the distinction between "not wanting to say anything" and making sure you have solid footing before you say anything. If you go with the "I don't want to say anything" route, then you don't get to complain to everyone later about what happened. (If you do that, then YOU are the douchebag).
If you have a concern, ask your opponent to wait before hitting their next shot and quietly and privately discuss it with your partner if you can. Legitimate (non-douche bag) issues arising between pairs/players regarding scoring, penalty strokes, etc. DO come up and SHOULD be discussed and resolved among the pairs/players involved prior to the continuation of play. I keep an Official USGA Rules of Golf booklet in my bag, and it will be available to anyone who has a question about a rule. However, I will not get involved in any questions about rule interpretation outside of my own match other than lending out my rule book. Any issues that may arise shall be resolved among ONLY the player/pair involved and in a fair and friendly manner which complies with the rules of golf.
If you choose to be a douche bag by breaking a rule or pressing an insignificant issue, keep in mind that you might earn the same treatment from your opponents-as well as the reputation of being a douchebag.
IMPORTANT NOTE: Being the rule-breaker is just as much of being a douchebag as calling out potential rule violations and/or douchebag conduct on someone else's part. If you are the guy who is "seeing what he can get away with" (e.g., using a foot-wedge to get a ball out from behind a tree or out of the rough, improperly replacing a ball on the green after marking it so that it is closer to the hole, or repeatedly being the ONLY guy who is able to miraculously find his ball when it appeared to all that it would be lost after it was hit, practice chipping/putting/rolling the ball on the green before finishing the hole, etc.), then you are breaking this rule by putting the other guys in the foursome in a position to even have to question the conduct.
REMINDER: DON'T BE A DOUCHEBAG!!!
