||A boy performs cunnilingus and a girl in a bra performs fellatio at separate times during a scene (he pushes her head toward his groin, we see his pleasured facial expression, then we hear a crunching noise and see his pained expression). Also, he removes her panties, first resulting in bats flying from her crotch and then causing a huge mound of pubic hair to become visible at the bottom of the screen; he cuts the hair with hedge trimmers and we see a shot of her bare lower thighs and knees before we hear her moan sexually. Then, while the two have intercourse, she thrusts on top of him while insulting him and slapping his face twice; he ejaculates in a huge, continuous spray that lifts and pins her onto the ceiling (we briefly glimpse the side of her bare body as she's flying toward the ceiling; the semen covers all but her bare shoulders and legs when we see her on the ceiling).
Lots of sexual innuendo (including sometimes graphic references to fellatio, cunnilingus, masturbation, homosexuality, prison rape, teacher-student sexual relations, and sexually transmitted diseases); also, it's implied many times throughout the film that one of the characters is homosexual.
Two couples kiss, caress, and moan in the back seat of a car; both girls' panties are removed (nothing sexual happens afterwards) and a boy supposedly removes his finger from the other boy's rear end.
A woman's head pops up from a man's lap and she wipes her mouth, implying fellatio. In another scene a boy pushes a sausage in and out of a girl's mouth, simulating fellatio.
Someone pushes a girl's face on a boy's lap (the boy acts as if she's chosen to perform fellatio on him).
A girl walks into an office and sees a woman smelling a pair of panties; also, when the woman uncrosses her legs, enlarged testicles fall out and hang below her short skirt for the rest of the scene (the woman stands behind the girl and briefly propositions her).
Two men make sexual hand and hip motions; also, a boy moves a stuffed animal's arm so that it appears to be masturbating.
A penis sticking though a glory hole in a toilet stall rubs a boy's ear (see Violence/Gore below).
[Nudity] We see a photograph of a boy's genitals; in a later scene he shows the picture to several others.
We see a couple of boy's bare backsides and several boys wearing towels and boxers during a locker room scene (one boy slaps several boys' buttocks).
[Nudity] In a female locker room, we see girls wearing bras, panties, and towels. A girl removes her towel and we see her left breast (and nipple) for a second.
A girl's sweater and skirt are ripped off while she's being chased, revealing her bra and thong panties (we briefly see most of her bare buttocks); she's sprayed with water and then suggestively runs her hands over her body in slow-motion.
Some passionately kissing, one involving tongue twisting.
A few girls in scantily clad attire briefly seen.
||Someone is stabbed repeatedly then sliced in the neck (a little blood is visible, and we later see the body being dragged away in a trash bag); also, four others are stabbed with a knife or a hook, sometimes repeatedly and sometimes resulting in visible blood (once we see the bloody knife, once we hear squishy noises during the stabbing, and once two people watch the stabbing but don't intervene).
Several people punch, kick, and stab a girl to death (some blood is visible).
In one scene, a girl is stabbed (her hands and shirt become very bloody), then she twists and breaks her own leg (we hear a crunch and see the broken bone), then her head is severed (she continues to talk) and the bloody head is thrown into a trash can.
A girl's chest is stabbed and we see a bloody breast implant stuck on the knife, as well as her bloody bra and hands.
Someone waving a hook around unknowingly stabs and kills several people (we hear slicing noises, then see several slightly bloody corpses lying on the ground).
A penis sticking through a hole in a toilet stall "impales" a boy through the ears (we later see him with a bandaged ear).
A girl is killed when she's caught in a garage door that opens partially.
A man jumps off a building to his death (we see him hit the ground).
Someone is shot (we see a bloody hole in the person's shirt) and a man shoots at several boys who've just shoplifted from his store.
In two different scenes, a girl is hit by a speeding car (we see the impact both times and see one of the girls flip high in the air); also, a car skids and hits someone, but the person gets up after a bit and appears to be unharmed. In two scenes a boy chokes a girl and shakes her by the neck; in one scene he also punches and kicks her repeatedly, then body slams her on the ground.
A boy hanging out of a moving car's sunroof is hit repeatedly in the face with tree branches, steps on a passenger's back and head, and, at one point, has a beehive stuck on his head (he seems unharmed afterwards).
A girl throws a vase and rolls a bike and piano down a staircase at someone chasing her; the piano hits another person instead.
A girl and a masked individual are involved in an extended fight scene: both are thrown against a wall, a lamp is broken over one's head, one is kicked through a door, and one is kicked in the face repeatedly.
A girl mistakenly beats a few trick-or-treaters with a bat (we see them lying on the ground afterwards.)
A man steps on a woman's foot (we hear a crunching noise.)
A man runs into a tree and falls.
