When a seated woman pinches her knees together as if all men are thirsty for what's between her legs, defying legal norms of presumption of innocence and societal norms of mutual respect and inclusion. This pathologically used gestural slander is part of a broader pattern within the institution of matriarchal oppression that has likely been in place since women took payment from guards, hunters and gatherers for sexual access and yet claimed the "oldest profession" for themselves. It shames and thus weakens men so they can be more readily manipulated to maintain their own oppression by continuing to protect and provide for women without regard for the merit of such women or their own well-being. It artificially bumps perception of scarcity/desirability of the sex that women sell, while highlighting its presence thus increasing it's subjective value. Only when all women and men sit with their knees at proportionally and anatomically appropriate distances apart, will they be able to live as equals.
All the women on the bus were womanpinching but I only found one of them attractive. It's too bad she hates and manipulates men.
