I don't know if this film was released in theaters or if it was made for television.
I saw it on television in the 1990s (USA), and I think the characters had hairstyles and clothes to match 90s styles.
It was about some teenage boys at a summer camp. The protagonist (who I think was blonde) really didn't want to be there. He was put into a cabin with several bunkmates, and one was a troubled kid who usually wore black clothes and slept upside-down (and I think he had red hair). He said something about it being because that's the way bats sleep. I don't know if that guy was supposed to be goth or emo or depressed or what, but he acted weird and usually refused to participate in group activities at the camp. Also the weird kid always had a toothbrush, and he was very possessive of it. He usually had it in his mouth and he would talk to it and claimed that it talked back to him.
I'm not sure about this, but the summer camp might have been for delinquents. The protagonist kid had to teach the others to work/play together, and to be proud of their group, even if it was a summer camp for rejects. So there was a sports competition or something, probably against other summer camp groups, and the kids had to learn to work together to compete against the others. At the end of the film, the weird red-haired kid showed a very drastic change of personality. He no longer acted depressed, he participated in sports, he was much more extroverted, had higher self-esteem, and I recall that the protagonist asked him about the toothbrush he had in his mouth. The red-haired kid smiled and said something like, "You know, toothbrushes sometimes say the darndest things!" and then threw it away to signify that he didn't need it anymore since he had learned to make real friends.
I tried searching for this with no luck. Anyone know this one?
