>>14958943what the term actually means is a girl that espouses views or opinions that she thinks will make her particularly receptive to male attention, even more so than women already are; generally these statements are purported to have an anti-woman nature to them but the term, as with other words and phrases as of late, has been ground down into almost meaninglessness, it's just a way of saying "someone i don't like."
in the original context, it's essentially a method for women to police other women in a sort of crabs in a bucket way for stepping out of bounds within the context of the sexual economy. think of it like this: imagine said sexual economy like a housing market, but the houses never run out. and the women called pick-me's continually sell their homes at low prices, turning the market from a seller's market (men appealing to women) into a buyer's market (women appealing to men). the ones throwing this term around are mad because they see it as bringing down their stake in this overall economy as well, because now they have to compete with an option that's more outwardly appealing to men. it's like calling them a union scab. it's sort of like calling them the female equivalent of a simp.
