I don't know why a good amount of women work like this, but they do.
The more women are interested in you, then the exponentially more women become interested in you. They will even fight with each other all over the same man rather than deciding to go after different men.
It's why celebrities basically don't even have to try, provided they're not completely repulsive. Women want them just because they're a celebrity. Then other women want them just because other women want them. This snowballs. And they don't even have to have good looks. And they can even be somewhat repulsive, as long as not completely.
Germaine should be better than this though. She's supposed to be goth. She shouldn't even care what other women are doing.
