Teenage rebellion stems from the desire to establish independence from parents. The narrator and his friends want nothing more than to be considered "bad characters", and the fact that this is how they want to be characterized is a statement of rebellion in itself. This certainly is not how their parents wants them to be viewed or behave, so having this type of reputation makes it even more desirable. To them, being "bad" means doing anything their parents and all adults would disapprove of. School has just ended for the summer, so the boys are drinking and sniffing glue, actions that are illegal and dangerous for the teenage boys. They are legally not old enough to drink, but they view drinking as something that makes them cool. As teens, they don't realize or care about the consequences of sniffing glue or driving while drinking. These actions also lead them to do things they wouldn't ordinarily do, such as rape.
