->''Close your eyes for a second... and sleep forever.''
-->-- '''{{Tagline}}''

A SlasherMovie from the year 1982, which was originally scripted by feminist writer Rita Mae Brown and directed by Amy Holden Jones (who wrote the first ''Film/{{Beethoven}}'' film).

Bunch of girls decide to have a SlumberParty with all that comes with the territory; skimpy clothing, booze, pot and perverted guys crashing it. Unfortunately, a maniac has escaped from a mental institute, and seeks to continue the deadly work that he started over a decade ago by carving them up with a power drill..

The film spawned two sequels: ''Film/SlumberPartyMassacreII'' in 1987, and ''Film/SlumberPartyMassacreIII'' in 1990.

The trilogy also had several [[DolledUpInstallment pseudo-sequels/spin-offs]], such as ''Sorority House Massacre, Cheerleader Massacre'', and ''Hard to Die''.

!!This massacred party has examples of:

* AchillesPowerCord: Hiding in the basement, Valerie picks up a portable circular saw and tries to run with it upstairs to confront Thorn, but it comes unplugged before she manages to get on top of the stairs.
* AffectionateNickname: Trish, Kim, and Jackie eavesdrop on Diane calling her boyfriend, and much to their amusement, find out that she calls him "Booboo".
* BehindTheBlack: As the slumber partiers change their clothes, they completely fail to see Neil and Jeff staring at them from behind the window, simply because the five of them are never in the same shot.
* BetweenMyLegs: The movie poster, as seen above. Also, notice the placement of the drill. The same shot (drill hanging between the legs) is done during one of the actual murders of the girls as well in the film.
* BigBad: Russ Thorn, the escaped mass murderer who likes to kill people.
* CatScare: Cleaning up the mess she made in the kitchen, Jana hears a strange scratching noise in her house. She goes to investigate, and pinpoints the source to a closet. She opens the door, and a screaming cat leaps out. How did it get locked in there? Nobody knows. The film then proceeds to do the same with pranking teens and a neighbor killing snails with a meat cleaver. At one point there is a streak of seven consecutive false scares before the killer shows up.
* TheCavalryArrivesLate: Just before the end credits roll, police sirens can be heard in the distance.
* CutPhoneLines: After making his presence known to the partiers, Thorn cuts the phone line to the house just as they try to call for help.
* DeadMansChest: Thorn hides Kim's body inside a fridge. Courtney discovers it when she's going to snatch a beer from it.
* DeadPersonImpersonation: Thorn briefly pretends to be the pizza guy behind the door of the slumber partiers' house. When they ask about the money they owe for the pizzas, he answer with his current body count.
--> '''Jeff:''' What's the damage?
-->'''Thorn:''' Six, so far.
* DoesNotLikeShoes: Trish, Kim, and Jackie are barefoot. The trope is downplayed however, since they're in a slumber party.
* DramaticThunder: Thunder rolls in the background as Thorn comes inside through the window, and starts creeping towards the unsuspecting Trish and Kim.
* EyeScream: After the pizza boy rings the bell, the partiers gather money to pay him and open the door. To their horror, an eyeless corpse falls inside.
* FinalGirl: Averted with Valerie who is a typical good girl, but isn't the only survivor in the film.
* {{Foreshadowing}}: The girls read the horoscope for Scorpio, which is Diane's sign, which states that she's going to "get ahead" with the opposite sex. She later finds her boyfriend decapitated.
* GenericDoomsdayVillain: Russ Thorn has no personality, or backstory that would give him some sort of motivation for the things he does. He's just some psycho who killed people in the past, got locked up, escaped and is now killing again.
* GoryDeadlyOverkillTitleOfFatalDeath: The title tells everything what potential viewer needs to know about the film; that it has gratuitous fan service and plenty of death.
* IllKillYou: Screaming in pain for getting his hand chopped off, Thorn starts screaming this word for word at Valerie before she slashes his stomach open.
* ImpaledWithExtremePrejudice: Thorn is finally killed when he jumps on a machete held by Valerie, and is impaled by it.
* ImpromptuTracheotomy: Thorn kills Mr. Canton, who is busy killing snails that threaten his garden by drilling through the back of his neck and lets go of it, just to show Canton's corpse to the audience.
* KnifeNut: The slumber partiers arm themselves with kitchen knives once they learn of Thorn's presence.
* MacheteMayhem: The saw failing her, Valerie picks up a machete in the basement to confront Thorn with.
* MaleGaze: There are lots of shots of female backsides and undressings.
* ManBitesMan: Neil desperately attacks Thorn with a knife. As they struggle on the ground Thorn bites him, takes the knife and proceeds to stab him repeatedly.
* NotQuiteDead: Mortally wounded, Thorn falls into a pool and as a relieved Valerie hugs her sister Courtney, he rises from it to attack them once more.
* OffWithHisHead: Diane leaves her boyfriend John.for a moment in his car. When she gets back, she finds his corpse with its head put back on top of it, ready for a scare and a scream.
* OnceIsNotEnough: As Thorn attack Trish and Kim inside the room that they barricaded themselves in, Trish manages to momentarily knock him out with [[BatterUp a baseball bat]]. She and Kim then start removing the makeshift barricade, ignoring the unconscious killer lying helplessly on the floor.
* PeekABooCorpse: Jeff tries to make a break from the house besieged by Thorn through the garage, but finds the backdoor locked. Then Diane's corpse drops from above and as he screams, Thorn attacks him from behind.
* PunkInTheTrunk: Thorn hides the bodies his victims inside a car trunk in Deveraux household's garage.
* ShoutOut: After the lights go out, Kim and Jackie mimic ''Series/TheTwilightZone'' theme when Trish tells them that the fuse box is in the (possibly spooky) garage.
* ShowerScene: An extended shower scene takes place after a ladies' basketball game.
* SlashedThroat: Thinking that help has arrived, Jackie rushes to open the door and has her throat cut with a swing from the power drill.
* SpoofedTheIronicFilmSeriously: The film was written as a satirical jab at the slasher genre for its victimization of women and excessive nudity. Its ''directors'' took it seriously, filming it as a straight example of the genre, resulting in an IndecisiveParody.
* ThisIsADrill: Thorn picks up a power drill from the telephone van where he commits his first onscreen murder, and uses it as his WeaponOfChoice for the rest of the movie.
* TokenMinority: Jackie is the sole African American member of the cast.
