Ok, Here we go:
Hypergamy (colloquially referred to as "marrying up") is the act or practice of marrying someone wealthier, or of higher caste or status than oneself.[citation needed] Although the term is not gendered, it is generally used by social scientists to refer to women marrying higher-status men, rather than to men marrying higher-status women.
Studies of heterosexual mate selection in dozens of countries around the world have found men and women report prioritizing different traits when it comes to choosing a mate, with men tending to prefer women who are young and attractive and women tending to prefer men who are rich, well-educated, ambitious, and attractive.[6] Evolutionary psychologists contend this is an inherent sex difference arising out of sexual selection, with
men driven to seek women who will give birth to healthy babies and women driven to seek men who will be able to provide the necessary resources for the family's survival. Social learning theorists, however, say
women value men with high earning capacity because women's own ability to earn is constrained by their disadvantaged status in a male-dominated society. They argue that as societies shift towards becoming more gender-equal, women's mate selection preferences will shift as well. Some research supports that theory,[7] including a 2012 analysis of a survey of 8,953 people in 37 countries, which found that the more gender-equal a country, the likelier male and female respondents were to report seeking the same qualities as each other rather than different ones.[8]
However, Townsend (1989) surveyed medical students regarding their perception of how the availability of marriage partners changed as their educational careers advanced. Eighty-five percent of the women indicated that "As my status increases, my pool of acceptable partners decreases" (p. 246).
http://en.wikipedia.org/wiki/HypergamyPay close attention to those underlined parts! What this is saying in the modern dating / marriage plan is two things:
1) She sees you for not only your looks, but for your assets and net worth.
2) She requires you to make MORE than her, so as her income rises, she will pursue the higher end of the food chain.
As talked about before, this isn't necessarily a financial decision or the only factor either! There is also social standing & status involved. This is where the talk about "the top 20% of men are dating / sleeping with 80% of the women" and the inverse is true for the other 80% of men. This is essentially what you see in the younger generations, especially college level ages and on into the late 20's.
Ok, so that was from the wiki; here it is in much rawer terms from the manosphere:
The theory is more like this, from what I have read. Hypergamy is a woman’s natural (which is to say, genetically wired) preference for a higher status male–that is, higher status than herself and also higher status than the other men in her field of vision and also perhaps higher status than men she has known in the past and even (at the extremes) higher status than most men she can personally imagine meeting. That cuts across a range of possible relationships, all the way from a ONS to marriage. In all cases, women naturally prefer the highest status man they can get. And sometimes they want so much status that they won’t settle on ANY man they could actually get.
“Status” has a varied meaning in this definition. Certain things correllate with high status, for intance money, prestige, social standing, etc. However a man can have all of that and still be low status because of low status intrapersonal behavior (i.e., needy schlumpitude). The highest possible status male would be rich, good looking, fit, well dressed, high social cache, high prestige job (preferably one which involves risk, physical risk being better than mere monetary risk), and also extroverted, dominant, the leader of his group of friends, able to command any social situation, and so on. However, women are wired to be turned on more by the latter BEHAVORIAL traits than by be the former SUBSTANTIVE traits. So, if you have have to choose one or the other, to get women, be socially dominant and a broke societal loser rather than socially awkward and a rich societal winner. But best to be both, if possible.
As to marriage, sure women want to marry up. But this does not exhaust the effects of hypergamy. Women can marry up–both intrinsically and in their own mind–and still ditch their catch because someone “better” comes along. That is hypergamy at work.
Also, when women are pursuing short and medium term mating, hypergamy has no less force. They always prefer the most socially dominant male they can get. This is often relative (A&B are both a little dweeby but A is more alpha than B and since I want someone NOW I choose A) but sometimes it is more intrinsic (A&B are both a little dweeby and even though A is a little more alpha, since I don’t have to have someone NOW, I am going to hold out for the Real Deal).
It’s not all about marriage. It’s about mate selection accross the range of circumstances.http://therationalmale.com/2012/03/13/the-hypergamy-conspiracy/
The female who becomes agitated and pretends to be bothered by the male gaze is very busily deflecting and distracting your attention away from a much darker and significant point she would strongly prefer you were not aware of – and would rather not discuss: her own “hypergamy”. Her instinctual desire to discard her current mate with no feeling or remorse when the opportunity arises to latch onto a subsequent mate of higher status due to the hindbrain impetus to find a male with the best ability to provide for HER OWN offspring (already spawned or yet-to-be spawned) regardless of investments and commitments made to her current mate.
You.
She is hardwired for this. By nature. The last 4 years don’t matter. Whether you paid admission for 4 to Disney World – when the kids weren’t even yours – won’t matter. That you funded her dubious flirtation with returning to school for a useless degree doesn’t matter. That you work 70 hours to earn 6 figures with marketable skills beyond knocking a ball around won’t matter. Even if you are obese and have the face to stop a clock, your $181 Million dollar lottery win makes all the difference. It doesn’t matter WHO you are… it only matters WHAT you are.
Hypergamy. Does. Not. Care.
As societal impediments (both economic and cultural) to the recession of binding monogamous relationships deteriorate, the validity of this theory is being rediscovered to the chagrin of men in the trenches and to the delight of the new social engineers up in the towers.
Hypergamy can make a woman forget anything. Humiliation. Morals. The emotional well-being of her children.http://www.mgtow.com/video/hypergamy-doesnt-care/ Evolutionary Psychology theory on the instinctual desire of humans of the female sex to discard a current mate when the opportunity arises to latch onto a subsequent mate of higher status due to the hindbrain impetus to find a male with the best ability to provide for her OWN offspring (already spawned or yet-to-be spawned) regardless of investments and commitments made to a current mate.

akin to the notion of "serial monogamy" acknowledged by mainstream culture.
Hypergamy is a savage natural instinct that finds social acceptance when many other such instincts such as polygamy do not.http://www.urbandictionary.com/define.php?term=hypergamy
