Funnily enough, it doesn't sound that bad or unreasonable when using that language.
It's really in how those words are defined in the male mind and then articulated to women.
Fit means whatever body is in vogue at the moment. It changes every few years. If you can achieve it naturally, get surgery so you do.
Feminine means fake. Fake, manipulated proportions, fake facial contours achieved through makeup, fake eyelashes, fake hair, fake personality, fake lack of competence, fake flattery, fake everything. Be a plastic barbie doll or a blow up sex doll. Just whatever you do, don't be you.
Friendly means always be pleasing, agreeable, amenable to whatever whim the guy has at the moment. Always be open and available to sexual advance or emotional need of the man. Make him feel seen and worthy. Tolerate and encourage him through his awkwardness and also his boorishness. Above all, do not throw up any personal boundaries for your peace of mind, space for yourself, or even your own safety.
Here we see that fit, friendly, and feminine is absolute shit. It's harmful to both genders.
