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.
Wall, also spelled The Wall and The Wall (TM) represents the point in a woman's life where her SMV has fallen to zero and men no longer give her preferential treatment.
The manosphere generally agrees that the Wall hits an average woman when she reach the age 30. However, women such as Lindsay Lohan hit the wall as early as 25 due to drug and alcohol usage.
Causes of the Wall
The Wall is caused by multiple factors which can be divided into physical and psychological.
A woman's physical attributes change as she ages. Her physical beauty peaks in her early 20's. By the age 30, her breasts will have began to sag, wrinkles and white hair will begin to show. Coincidentally, her fertility begins to decline.
The psychological aspect of the Wall is further subdivided into internal and external.
Internally, a girl begins her life with love and care from her parents. Later she proceeds to school and possibly college. Up to this point in time all her expenses were paid for by parents, the government or a loan guaranteed by the government. More precisely, her income (likely $0) is less than her expenses.
From the period after graduation and before 30, she is in the peak of her beauty and maximum SMV and MMV. As such, men readily treat her to free food, drinks and social events. This enables her to continue a lifestyle in excess of her own income.
By the age 30, all these subsidies would have been depleted. Meanwhile, she may have a student loan to repay. Suddenly, her income must be greater than her expenses to remain solvent. Career-wise, 30 is around the age where meaningful promotions become substantially more difficult to obtain. As such, a woman's internal situation cools down notably after she turn 30.
Externally, all men prefer young girls. This isn't a problem when the woman is in her 20's. By the time she hits 30, her male peers who are serious about marriage would have been married or in an LTR. Those remaining peers interested in marriage would have moved on to younger and more fertile girls. This leaves the pool with men that are not interested in LTR or men that other girls have repeatedly refused.
When a woman asks "where have all the good men gone?", she has hit the Wall.
The manosphere openly practices discrimination against women who hit the wall (AKA post-wall women). Judging women on the basis of her beauty and fertility is as fair as women judging men on the basis of his income and status.
For marriage and family purposes post-wallers are bad choices. Post-wallers spent their 20's ignoring / rejecting marriage. At best, she is a person incapable of compromise and making practical choices - the must have skills for a family. At worst, she is a slut trying to con a beta so she can continue to ride the carousel.
For sexual pleasure purposes, a man is better off with a prostitute. They are younger and more professional. The cost for one session with a prostitute is comparable to the costs for dating a post-waller. And if a post-waller is offering sex for free, chances are, she is trying to get the sperm.
The infamous Wall a woman reaches (or slams into as the case may be) is somewhat of an ambiguous term that was actually coined by catty women long before the manosphere came into existence. It used to be a relatively less combative term that women used for one another in an effort to disqualify a sexual competitor. A woman implying another woman had “hit the wall” was marginally more polite than calling her a slut, but the latent purpose is still the same – disqualifying a sexual competitor from men’s mating considerations.
