There are lots of mature sexual themes.

There is a brief snippet of an online porn video, but no explicit nudity is seen. A woman is in panties and a bra, and a man talks dirty to her (graphic dialogue). He briefly reaches out and wraps his hand around her neck, pretending to choke her, as part of a role-playing game. It cuts to later in the video, where the man is supposedly having anal sex with her. She is leaned against a wall and is seen from the back being rocked back and forth while exclaiming "f**k me!" No nudity, but still graphic considering the context of the video. All the while, the name of the site "Nasty C*mholes" is put in large letters in the bottom right corner of the screen. Shortly after, it is revealed to us that we are seeing this because a teenage boy is masturbating to it while watching it on the computer. We see him shifting in his chair #no nudity# and we hear him breathing heavily. His friends knock on the door and he puts everything away, embarrassed. When his friends come in, one says, "I smell c*m" tauntingly to the boy.

A teenage boy bullies another teenage boy by giving a very descriptive and graphic explanation of how he had sex with the boy's sister. It is not revealed if this ever actually happened or not, but the boy tells it like it did. He says her "p***y was so wet" and "all you have to do is brush against it." Also, "last time she was s**king my d**k, it only took me a minute to come all over her face." The boy he is telling this to is obviously very upset and sits there in silence.

A teenage boy stares at his teacher's legs, breasts, and butt while she teaches at the front of the class. She is wearing a shirt skirt, but nothing too revealing is seen. A large portion of her breast is seen briefly when she leans over her desk. There are extreme closeups on all of these things.

A boy and girl are shown making out in the background during a scene in a sequence that is around two or three minutes long.

A man jokingly tells a boy to tell his mother to call him because he "hasn't seen her last night."

A girl tells a teacher that a boy wants to make a porn out of a video assignment a class is given. The teacher says "there will be no fluids, bodily or of any other sorts, permitted around the camera."

In order to get a teenage boy to speak, a counselor makes perverted jokes with him. He first says, "your mom has such big crabs, I ride them to work." The boy replies by saying, "your mom gets "f**ked for cash."

We see, through a webcam, a teenage boy masturbate to a porn. We hear the sounds of the porn in the background, and we see the boy bobbing up and down, but we do not explicitly see him manually stimulating himself. We see his face contort as he breathes heavier, implying that he had ejaculated. He pauses the video at this part and the image of his face is lingered on for a few seconds before the camera moves.

A counselor asks a boy if he likes to watch porn and the boy replies "yes." The boy goes into detail about the type of porn he watches, but it's not very graphic. He says that there is a man in the porn the camera man who scares the women before having sex with them.

A few clips of popular Internet videos are seen in the intro to the film. One shows a man trying to do a trick on a bike, but failing and doing a painful face plant on the ground (most likely meant to be comical). Also, a video taken at the hanging of Saddam Hussein is featured in this montage (not explicitly violent, but eerie and disturbing). Also, a very graphic clip of a dead body and a disembodied leg. This clip is presumably in Iraq, for American soldiers and Middle-Easterners are seen gathered around. Very violent and it is lingered on for quite some time. It sets the mood for the film, but will be extremely disturbing to most.

A very brief fist fight breaks out between two male students in the background in a scene. It is hampered by a group of teachers before it becomes too violent. This incident is not particularly focused upon, due to it being not in the central view of the shot.

A boy hits himself in the face several times when he is angry with himself.

The main character gets in a large scale fist fight with his best friend while screaming and cursing at him.

A group of boys watch and rewatch an online clip in which schoolgirls fight each other quite viciously while classmates watch and cheer. One is hit over the head with a bottle and falls to the floor.

There are extended scenes with graphic sexual dialogue and epithets.

5-10 uses of "f**k," most of which are used sexually (Closer to 15 by my count),

There are also very occasional uses of religious profanity.

Teenagers involve themselves in drug trade with other students in a boarding school.

A boy smuggles a bag of weed and vodka into a school, hiding the weed in the front of his pants beneath his belt and the vodka in water bottles.

There are some emotional and gut-wrenching scenes.
