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.

Szabo Principle

The Szabo Principle is the simple rule that when sitting an scholastic examination, the person sitting directly adjacent to you is likely to have the current answer incorrect 60% of the time.

Me: *Looks over to try and find answers from the person next to me during an exam*

Friend: “Don’t do that! The Szabo principle states that the answer you’re looking at is 60% likely to be wrong!

sexclusion principle

When determining where to place electrons in atoms, three rules are generally used: the Pauli exclusion principle, the Aufbau principle, and Hund's rule. The Pauli exclusion principle, from which the pun is derived, states that no two electrons (or indeed any fermion) can occupy the same atomic state. Therefore, any electron orbital is limited to two electrons: one with a spin, and the other with a − spin. The Aufbau principle states that lower energy orbitals are occupied previous to high energy orbitals. Hund's rule states that electrons will try to fill orbitals individually, and only pair up when every orbital has a lone electron in it.

In the comic, electrons are being equated to people, and rooms (or couches) are equated to orbitals. The reverse of Hund's rule is then followed: people will try to pair up in a room first, and only when all the couples have done so will rooms be allocated to single people. The Pauli exclusion principle here means that only two people can occupy a room at a time (should those people be romantically involved). The Aufbau principle therefore means that more restful rooms are filled previous to less restful rooms.

The title text jokes about drunken party-goers, who ignore the Pauli principle perhaps out of inebriation. They then end up partying and sleeping together with many people in the living room, leaving the roommate stuck in the third desirable location, the hall lounge.

Donkey Principle

The well-established, but long forgotten, rule of law that you will honour your obligations and treat your counterparty to a deal with the level of deference and respect due to them as though they had a compromising photograph of you with a donkey.

Tim: Hey Vinnie, how'd you go getting out of that crap million dollar deal you'd struck with KK?

Vinnie: No good mate, I forgot about the Donkey Principle and I had to suck it up and pay him his loot.
