There is a few sexual referencec through the movie

Some bullies are teasing a kid multiple times. They make him and another man lay on top of each other etc... Not in sexual ways

Minor.

There are fistfights in the movie, but there are no major injuris. (Broken Noses etc...)

Fuck, Shit, Hell are used a lot of times

Some Sexual References

Two or three middle fingers

The bullies smoke and drink through the movie

Talk about drugs

The movie is very emitional and depressing, it's about a troubled boy who is bullied at school. He is later trown out of his home and he is nearly commiting suicide

One boy steals dynamite and wraps it around his body. He then enters an school, and he is convinced not to blow up

The second half if the movie is much more intense than the first half
