Similar to "selective memory". When one claims having high principles and moral values only when it works in their favor. Often used as an excuse to avoid hurting someone's feelings.

Daughtery Principle

The Daughtery Principle, named after American football coach Duffy Daughtery (1915-1987) of Michigan State University, states that: “A tie is like kissing your sister.” While both evolutionary psychology theory and sociological theory would predict that this familial phenomenon would lead to osculatory outcome dissatisfaction, it has not been systematically tested except possibly in West Virginia and Vermont.

Football, basketball. and basketball have such a horror of the Daughtery Principle being enacted that play continues through overtime or extra innings until the tie is broken.

Berger's Permutation Principles of Divisibility

1.) Berger's First Permutation Principle of Divisibility states that all permutations greater than 3! are evenly divisible by 6.

2.) Berger's Second Permutation Principle of Divisibility states that all permutations greater than 4! are evenly divisible by 12.

The "!" is mathematically denoted as "factorial."

1.) In Berger's Permutation Principles of Divisibility, 3!-a! are ALL divisible by 6 a y number of times.

2.) In Berger's Permutation Principles of Divisibility, 4!-n! are ALL divisible by 12 an x number of times.

Principle of Least Interest

In a two-party relationship, the party exhibiting the least interest in the relationship holds the most power. This is due to the (albeit often false) presumption that relationships are an efficient economy, and that one party would only be more interested if the other is inherently more valuable.

Johnny wanted to send Daphne flowers after their first date, but since he asked her out in the first place, the Principle of Least Interest dictates he will be more likely to score with Daphne in the long run by waiting for her to make the next move.

Roger Rabbit Principle

It is ok as long as it is also funny. From the scene in which Roger Rabbit escapes from handcuffs:

Eddie Valiant: You mean you could've taken your hand out of that cuff at any time?
Roger Rabbit: No, not at any time, only when it was funny.

"Wow, what you just did was incredibly offensive."

"That's OK, because it was also funny. You know, the Roger Rabbit Principle..."

Heisenbro Uncertainty Principle

Combination of "Heisenberg Uncertainty Principle" and "bro." A bro cannot be both a bro and a boyfriend/husband at the same time. If he's with other bros, he acts one way: usually vulgar and rude. If he's with his girlfriend/wife, he acts another way: sweet and charming. He can never act exactly like a bro if he is with both bros and his girlfriend or wife.

One often observes the Heisenbro Uncertainty Principle at weddings.
