Manic Pixie Delusional Idiot.
I thought by trying to turn myself into the opposite of every female stereotype - super into sex, not into commitment, loves sports and booze, not into "emotional BS," not into make-up or standard fashion, not into gifts, said PMS was a load of crap, etc. - guys would be dying to be with me. They would gush to all their friends about how I was SO COOL and NOT LIKE OTHER GIRLS.
Turns out that being a big fake isn't that attractive at all.
