There is a scene towards the beginning of the film where it is implied that a girl and boy have sex

A guy at a party mentions that he only came to get laid.

A girl tells Veronica that her date with Kurt was detailed. A boy says to Veronica something about having a sword fight in her mouth (referring she gave them blowjobs) but she truly didn't.

"Fuck me gently with a chainsaw" is said by Heather Chandler.

A bully grabs a boy and forces him to say "I like to suck big dicks". After saying it, he makes impressions of it.

A boy and a girl kiss a few times.

An older boy (university age) asks a (school age) sick girl to have sex with him. He lies on a sofa when she gets up and walks away from him.

A girl burns her palm with a cigarette lighter socket and is in visible pain.

A bully grabs a nerdy boy and forces him to say "he likes to suck big dicks" and smacks the back of his head for retaliating.

Two boys push a cow and two girls get covered in its excrete.

Not a lot of violence. It happens once in a while.

The overall violence is mildly graphic.

A girl vomits.

A game of croquet is held, with three girls (all "Heathers") using another girl's ("Veronica"'s) head (not particularly violent, just played for laughs)

The results of the fight are shown as the two characters leave, with both of them bloody and bruised.

One of the most famous lines from the film is "Fuck me gently with a chainsaw, do I look like mother Theresa?"

The F slur is used once by a guy, and then a girl.

A police officer also says the F slur.

The 'f' word is used 15 times, the 'a' word over a dozen times, the 's' word dozens of times, "bitch" at least 3, "hell" at least 3, "damn" at least a dozen times, "prick" at least once.

One character gives another the middle finger.

Teen characters smoke and drink throughout the film although drugs is not the main theme of the film.

A stoner girl smokes a joint in the school bathroom.

This is a black comedy with some intense moments.

Nothing overly intense (maybe the shootings in the woods and the final scene) but the whole theme of the film is rather dark, with comedic/humorous undertones).

The movie is about teenagers murdering other teenagers and setting them up as suicides. Many people may find this and several pieces of the content disturbing, despite the fact that it is played for comedy.
