Faguet's Principle

a theory that states that girls only talk to guys who are either (a) gay, (b) foreign, or (c) a combination of these two characteristics.
Guy #1: Dude, why do chicks dig that foreign kid so much?
Guy #2: This is Faguet's Principle in action - not only do they dig his sexy foreign accent, but he came out last week too.

selective principle

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.
Chip said he wouldn't sleep with Karla because she's married and that he has principles, but Chip continues to sleep with Nicole who's also married, but Brazilian and super hot. Chip has selective principle.

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.

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.

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.
