as you said, LVM is "low-value male." Frankly, LVM would be closer to "normie." An average man is a LVM according to them.
They needed a term that was even more insulting, so they came up with NVM: no-value man.
Their quest is to find a HVM which means all the things you would guess it means: rich (of course) but also tall, attractive, etc. What's hilarious though, is that a man can be all of those things, but if he rejects her ...if he has the UNMITIGATED GALL TO REJECT ME!! A LITERAL QUEEN!! (rageface.jpg) ...then he's not a HVM.
And keep in mind, as you read their stuff, these women are by-definition used-up whores. How do I know this? Because no hot, young woman (you know, a "high-value" woman) complains about men (except to humble-brag). A woman in her prime is treated well, even by chads. Even chad will consider giving commitment to a fit 20 year old.
People (men and women, us and them alike) only complain when they don't get what they want. Women go through a phase in life (unless they're fat) where they can get what they want. The fact that FDS is complaining proves that they are past that phrase of life - it proves that they wasted their youth and failed to secure commitment. It proves that they're failures.
So a failure FDS will approach an objectively HVM. The HVM will look her up and down, and then decide she's only good for sex, and only if she doesn't speak. FDS will drop a bunch of rules on him including (hilariously) no sex before marriage. The HVM will laugh and walk away. The FDS will then angrily claim he was a LVM the whole time.
Cope levels that high shouldn't be possible.
