Sexclusion

When two out of three people in a group are in a flirtatous mode and obviously want to bang each other while completely exluding the third wheel.
While Bettie and Harold fondly caressed each other, Greta was in the corner feeling pangs of sexclusion.

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.

A delusional ex you want to auction to the lowest bidder.
Honey sugar my selusionex from Jersey City showed up this holiday season from the blue saying you must be so hard and wet for me; Forget I crushed you being a total loser and douchebag the last time I texted or that was fifteen years ago given time just moving forward with no two tones about it.

I held an auction for my selusionex hoping for a 0 cent bid.

It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.

Man, I just watched the funniest nutshot video ever.
