Courtship dating crystal castles lyrics
If you are a guy, she'll probably challenge you to a fight or a drinking competition, win both and then take an aggressive lead in anything sexual that happens, before kicking you out the front door the following morning or teasing you mercilessly if she lets you stay some more.
In short, she is a young woman with the personality of a Fratbro. Despite (or perhaps because of) their masculine personalities, Lad-ettes are generally heavily sexualised and are not likely to let any males in the company forget they are female.
And, for the ideologies for and against her, see Real Women Don't Wear Dresses and Vasquez Always Dies.
Male characters may well be sexually interested in Lad-ettes for various reasons, whether it's appreciation of their masculine personality and interests, because they don't disapprove of laddish behaviour, because Lad-ettes have lower body modesty and a more practical attitude than more "ladylike" women and hence show more skin, or simply because of their assumed openness to the idea of casual sex.
In turn, a Lad-ette can be utterly shameless in exploiting male sexual interest for her own personal advantage.
Compare and contrast with other tropes about women who look/behave in a traditionally "masculine" way: the Tomboy (she might have been one when young); Bifauxnen (where the girl can effectively pass as a male - though ironically while lacking most of the 'masculine' behaviour of the Ladette); her ancestor, the Pirate Girl; and her great-grandmother, who shares some of her mannerisms and points of view, but retains a more feminine image: The Flapper.
Also compare the Butch Lesbian, with which this trope may or may not overlap.
