Quote 1
"Some years ago […] Karl did a couple really bad things, which were pretty scary—well, really scary—and so a lot of kids that don't know him call him 'Psycho Shoemaker,' which really hurts his feelings and is so unfair, but it also means that some kids who don't know him are scared s***less of Karl."

Karl may be the school psycho, but at least his friends know who he really is. In particular, it's kind of awesome that Bonny defends Karl, even though they broke up because he didn't want to drink with her anymore.
