This is a pun on the {{w|Pauli exclusion principle |Pauli exclusion principle}}, which states that no two identical fermions (such as electrons) can be in the same state at the same time. In this case, the roommates and their guests are the electrons, which also means that only two people can be in any one room, or orbital. (That two are in a room instead of one has to do with spin; electrons with opposite spin are not considered to be in the same state, and thus may share an orbital. There are only two available spin states, however, so orbitals cannot contain more than two electrons.) An orbital describes the probability of finding an electron in a given space.

Orbitals
Except the people filtering in late are the partiers, so you end up with drunken makeouts in the living room and the next roommate to return home has to sleep in the hall lounge orbital.
Title text: Except the people filtering in late are the partiers, so you end up with drunken makeouts in the living room and the next roommate to return home has to sleep in the hall lounge orbital.

Explanation

This is a pun on the Pauli exclusion principle, a principle that two identical fermions (particles with half-integer spin like electrons) can not be in the same quantum state at the same time and location.

In this case, the guests are the electrons, only two people can share a single room (or orbital, describing the probability of finding an electron in a given space). But the different spins here are just the different chromosomes of females and males. The roommate, female or male, has to occupy an other orbital, because there are only two available spin states possible for fermions: +1/2 and -1/2.

The title text jokes about drunken party-goers, ignoring the Pauli principle, partying and sleeping together with many people in the living room. The roommate ends up in the hall lounge.

Transcript

[A person is holding up a pointer in front of a diagram of a dorm apartment. On the diagram, there are two connected pairs of dots in each bedroom, and one dot on the couch.]
Cueball: Thus, once all the dorm bedrooms are occupied by romantic pairs, additional roommates are forced into less restful "living room couch" orbitals.

Discussion

The explanation implies that the romantic pairs must be male-female. I do not see this restriction in the comic. 108.162.219.223,

When I finally came to college, this comic was always on my mind. Then came a rather... er... covalent night. Except I didn't actually form the second pair, but came really close to doing such. But even then this comic always came to mind. International Space Station (talk) 08:59, 8 October 2015 (UTC)
