I'm writing a story. One of the main characters will be a boy with bad reputation. There are a lot of gossips about him around the school. Like, he hates the red colour, rock classic and brown eyes; once when he had detention he smashed up the class; he did something horrible to his ex-girlfriend and because of that her parents decided to move; and they say he ate a cat.

What else can they say? It doesn't have to make sense, I just need some gossips that would make people aware of him - he doesn't want to have friends in his high school.

(He's made some of them himself and he's pretty satisfied with the effect.)
Also, he is believed to collect virgins' skulls.

He smokes cigarettes but everyone thinks he's on drugs as well.
He skips classes and he's a really bad student, often goes to detention and visits school psychologist and the principal. History teacher truly hates him.
