No, I don't give a fuck about how it tastes. Piss off. She likes sports, beer, cars, swearing, fighting, and sex in a stereotypically masculine way. She is crude, rude, often hygienically challenged , and cheerfully ignorant and aggressive. 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. She is the Lad-ette. 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. They are also generally attractive in an Unkempt Beauty kind of way; a genuinely ugly Lad-ette is very unusual. She may occasionally invoke Blemished Beauty : a nose that has obviously been broken at least once or a well-placed scar may be part of her charms.
Male characters may well be sexually interested in Lad-ettes for various reasons, whether it's an 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. Or heck, some guys just like a girl who is going to take charge.
In turn, a Lad-ette can be utterly shameless in exploiting male sexual interest for her own personal advantage. Sometimes, this woman's personality is explained by her having grown up with brothers or been raised as a boy.
Sometimes many of her friends were boys, or are from rough, unhappy, flawed backgrounds. Feminine and masculine behavior are culturally defined, so another common reason for this trope is that the woman in question comes from a wildly different time or place. Note that this trope is not usually Truth in Television. Real people yes, even frat boys don't act like this all the time.
