As an example, let's remember that she's quite taken with everyone's least favorite anatomically correct leering rubber homunculus Ned Tanner. Something weird in her finds his hideous visage (which personally reminds me of the rictus grin of a dead man who'd been trod on by a stampeding elephant), misshapen body and the surprise in his boxers almost as fun as she finds the revolting habit of spitting watermelon seeds onto other people.
That being said, it's not enough that she has the tastes of a defiant, naughty and weird little girl. She must also go out of her way to detest things that almost everyone else enjoys. This is why, for instance, she makes a point of shunning video games and other things cybernetic; the idiot elitist veneer over the anarchic child with the incomprehensible tastes allows her to pretend to be a serious adult so as to hide her true motive: a fear and hatred of doing what's expected of her and following the rules. Granted, growing up and being tyrannized by a wanna-be Brit with his head firmly planted in the nineteenth century can mess with a person but there comes a point where most people would seek help.
