Alpha – Leader. Somebody who displays high value, or traits that are valued by women. Alpha can refer to a man who exhibits alpha behaviors (more alpha tendancies than beta), but usually used to describe individual behaviors themselves.
AMOG – Alpha Male Of Group.
AFC - Average Frustrated Chump (Also known as beta)
Beta – Traits of provision: either providing resources or validatation to others, women (and perhaps men). Beta traits display low value to women if they are are put on too strong or too early in meeting- giving without equity. Beta can be used to describe individual behaviors, as well as people who have an overwhelming amount of beta properties (opposed to alpha).
Blue Pill – From The Matrix and its sequels. The path of conformity with Society’s expectations; the state of being unaware of the problems engendered by society. Compare with “Red Pill,” below.
Carousel – Better known as the “cock carousel.” The period of time in a woman's life where she successfully exploits her sexual value and maximizes her hypergamous tendancies by having sex with as many alphas as possible. Usually happens between ages 18 - 27. Often ends when the woman hits the wall.
DHV – Display of Higher Value, the accomplishment, anything that improves your sexual market value in the eyes of another.
DLV - Display of lower value.
Feminism – ”A doctrine built on the pre-supposition of victimhood of women by men as a foundation of female identity. In its goals is always the utilization of the state to forcibly redress this claimed victimization. In other words, the proxy use of violence and wealth appropriation. In whatever flavor, and variation, these two basic features are common to every doctrine using the label feminism. Feminism is therefore, a doctrine of class hatred, and violence.” (John The Other, “Why not date a feminist?” A Voice For Men, 4 June 2012.)
Friendzone - See Orbiter.
Game – A loosely based set of behaviors specifically designed to increase attraction.
Hypergamy – The instinctual urge for women to seek out the best alpha available. This is marked by maximizing rejection (therefore women are the selective gender). A woman will vet her alpha through various shit tests to ensure his "health" on the alpha scale. She is conditioned to recognize a declining alpha, as hypergamy also tends to continue seeking out higher status males even while with an alpha male. Shit tests allow her to prepare herself for eventually leaving when a new higher status male is found. If the male fails shit tests to a great enough degree, it will effect her feelings for him. He will effectively lower his sexual market value in her eyes. This will enable her to jump to the next male with ease and little remorse.
Incel - Involuntarily Celibate.
MGTOW – Men Going Their Own Way; the growing contingent of the male population who are saying “Fuck It All” to the Mating Dance.

He will stick around her and constantly validate her whenever she requests it. Also known as "friendzone."

Snowflake - A woman who tries to persuade a man that she’s somehow unique, different, or special by playing up her good girl resume and downplaying her bad girl resume. When used as a verb, snowflaking refers to the argument she puts forth to justify her claim.
The Wall - The point in a woman's life where her ego and self-assessed view of her sexual market value exceed her actual sexual market value; the beginning of the decline. Usually occurs as a wake-up shock to women when they realize that their power over men was temporary and that their looks are fading. This usually results with first denial and then a sudden change in priority towards looking for a husband. Even after hitting the wall, many women will squander a few more precious years testing her SMV with alphas to double-check, hoping her perceived decline was a fluke, this will make her even more bitter when she finally has to settle for a worse-beta than she could've gotten before because of squandering her youth.
