In RP world, both men and women have a "value" that is set by certain parameters. A woman's only value is solely how conventionally "hot" she is. But a man's value? That's up for the toss. It's a weird combination of his financial wealth, his social skills (which in RP world is determined by how much of an asshole you are) and his physical fitness, with no exact ratio.

When a feemale leaves a guy, it's always because either his "value" dropped, or because she'd found someone with higher "value", which is what they call "hypergamy".

Terpers are incredibly insecure, and are constantly afraid of women leaving them, which is why they believe that unless they keep up on all fronts (that is, be the richest, most physically fit and most asshole person alive) their women will leave them for someone better on those accounts.

You can already see this argument cannot be refuted because it's so vague and shaky as it is- terpers never define what makes a woman determine if a guy has high enough value or not. A guy can be the richest, most fit guy in the world but if the woman leaves him for a poor, skinny asshole they'd just say "you weren't alpha enough, hypergamy!" but the same would be said about a woman leaving a poor, fit asshole for a nice, fat rich guy. Even if a girl leaves a rich, fit asshole for an ugly, poor nice guy, they'd still find some way to make a case for hypergamy. And if a girl just leaves a guy without moving on to another guy, they'll usually tell the guy he dropped in "value" somehow by not being rich/fit/asshole enough.
