The 1/19 Rule 

An excuse used when someone makes a leap in logic with no evidence behind it that leads to the solution of a puzzle regardless.

"Wow Ty, how did you know it was Mr. Red in the dining room with the knife?"
"It was quite simple, I just applied The 1/19 Rule and knew instantly."

The Tip-Toe Rule 

When two people meet, usually online in an online chat room, and through common hardships, life experiences, witty humor, and intellect fall in love. Both parties are madly in love, but for for one reason or another are afraid of telling the other party. The tip-toe rule is designed to keep one party from saying the words "I love you" at a time when both are emotionally vulnerable and are afraid from falling off an emotion cliff with no bottom. It is believed by respecting this boundary that these two people will be able to build a relationship meant to endure, and last the test of time.

The tip-toe rule is a rule deisgned and created by two people to protect their fragile relationship. Usually a fool-hearty decision because there are no guarantees of a tomorrow.

"Dexter sat down looking longingly at the object of his affection. His own recently jaded heart wanted to tell the woman of his affection that he loved her with all his heart, but was afraid of falling into the abyss from which he could never climb. In fact, in a series of bad comedies, he unknowingly threw himself down into the abyss by abiding by the tip-toe rule. To this day, Dexter has never been able to find his way out."

The Aaron Rule 

From Urban Dictionary:
The Aaron Rule: As made famous by Mr Aaron Graham (aka Semitence), an unpopular yet prolific gamer based in Melbourne Australia. The rule states that one must never listen to Aaron in any matters pertaining to game play, competitions of any sort or anything where he could potentially “win” or “gain” something. Care should be taken as seemingly good advice for the unprepared listener will always end up in unforeseen negative consequences to said listener and positive advancement of Aaron. This results in the shortened version of this rule (although technically incorrect) “never listen to Aaron”.

Aaron: “I think you’ve got a good move here... just move your warrior to the east.”
Players: “Remember the Aaron Rule!”
Player moves warrior west.

The Golden Rule

"Treat others the way you wish to be treated."

It seems that most politicians -- especially Joe Biden and Donald Trump -- have forgotten The Golden Rule. It's time to reintegrate it into society once more.
