Much of female fashion and beauty effort is a form of intrasexual competition. It signals status to other women and serves a "mate guarding" function, as studies show men are often less discerning about the nuanced differences in high-status attire.

For hyper-successful women at the apex of their fields, the optimal mating strategy is to choose a partner from a completely different 'status game' (e.g., an entertainer marrying an athlete). This avoids direct professional comparison and competition, allowing for a relationship based on complementary, non-overlapping forms of prestige and competence.

As a competitive tactic, women advise female rivals to delay having children and prioritize their careers more heavily than they would for themselves. This serves to subtly suppress the reproductive success of competitors under the guise of helpful advice.

The speaker introduces "mate suppression" as a twisted biological impulse, particularly prevalent in toxic femininity, to harm the reproductive chances of perceived rivals. This drive manifests in behaviors that sabotage others' attractiveness or access to mates, explaining seemingly irrational social rules that secretly aim to handicap competitors.

By branding traditionally attractive masculine traits like dominance and aggression as 'toxic,' women can manipulate the mating market. This sabotages rivals' ability to select high-quality partners by steering them toward less desirable mates, thereby inhibiting their reproductive success.

Contrary to popular belief, women's elaborate grooming and dressing are often not for men, but are intrasexual signals of aggression, dominance, and social status aimed at other women. An attractive woman signaling this way is seen negatively by rivals.

The "swag gap" critique, where women lament their male partners' lack of style, is a form of failed cross-sex mind reading. It applies female standards of appearance-based status to men, who often signal high status through other means, including indifference to appearance.

Highly technical, male-dominated pursuits like heavy metal guitar function as an intrasexual status competition. They are not primarily for attracting women directly. Rather, men compete to establish a hierarchy among themselves, and women are then attracted to the high-status winners.

The "having a boyfriend is cringe" trend, promoted by high-status women, may be an unconscious evolutionary strategy to suppress the reproductive success of other women, thus reducing competition for desirable partners.

A study found that men’s real-world sexual success was highly correlated with how intimidating other men found them, not by how attractive women rated them. This suggests female mate choice is less about direct selection and more about passively choosing the victors of intra-male competition, validating a 'male competition theory' of attraction.

A subtle form of female competition, the "bless her heart effect" involves disguising reputation-damaging gossip as an expression of concern. This allows an individual to subtly attack a rival while maintaining plausible deniability and a pro-social image.
