''The Opposite Of Sex'' is a 1998 {{black comedy}} starring Creator/ChristinaRicci, Martin Donovan, Ivan Sergei and Lisa Kudrow. The main protagonist is Dede Truitt (Ricci), a troublemaking teenage girl who leaves after home after her father dies and moves in with her gay brother (Donovan). After a few weeks she seduces his boyfriend (Sergei) into bed and ends up pregnant. After that, the two of them take off to LA, emptying the brother's bank account along the way.

!!'''The Opposite Of Sex''' provides examples of:
* {{Angrish}} - Lucia, ironically one of the most articulate characters in the movie, delves into this when her frustration gets the best of her, with her speech devolving into a string of spat-out obscenities and monosyllables: "Fine! Goddammit! God! Fuck! Shit!"
* AshesToCrashes: Played with. Dede steals Tom's ashes and uses them to blackmail Bill and Lucia. [[spoiler:She later gives them back unharmed, admitting it was low, even for her, to steal them]]. [[PetTheDog She even double-bagged them]]!
* BabiesEverAfter: Both Dede (and Bill by extension) and Lucia end up with kids.
* BabiesMakeEverythingBetter: Played with. The end of the film [[spoiler: has Dede preparing to leave the baby with her brother, but cuts away as she insists she won't go back. It's left open either way.]]
* BetaCouple: [[spoiler: Lucia and Carl]]
* BiTheWay: Matt
* BitchAlert: In a variation, both Lucia and Dede
* BlondesAreEvil: Dede
* BrainlessBeauty: Matt is a male example. It's often [[LampshadeHanging lampshaded]] by Dede.
* BrickJoke: Lucia tells Dede she pronounces her name "loo-sha" because of her sisters Marcia and Tricia when her parents actually named her "loo-chee-ah". Later on she gives her name to a credit card company and spells it out for them. After a pause she snaps "Yes, I know how my own name is pronounced".
* BulletHolesAndRevelations: Struggle for the gun version was used, including the subsequent fakeout, which is {{lampshaded}} after the reveal, with the line [[spoiler: "What you thought I'd be the dead one? I'm the fucking ''narrator'' guys. Keep up!"]]
* CharacterDevelopment: Almost the first thing Dede's narration tells us is that this isn't going to be a story about how she grew as a character and became a better person. At the end, she faces the possibilty that she has changed, but she still stubbornly declares that she won't turn into a better person in front of us, and [[BreakingTheFourthWall shouts at the camera]] until it (and the audience) goes away.
* ChekhovsGun: Dede is shown packing a gun, and helpfully informs the audience, "This is {{foreshadowing}}. [[ViewersAreMorons Duh!]]". Despite the fact that she toys with being an UnreliableNarrator, it does get used later on. [[spoiler:And just when you think it's outlived its usefulness, it comes back a second time]].
* Creator/ChristinaRicci: In one of her earliest "adult" roles.
* DeadpanSnarker: Lucia.
* DefrostingIceQueen: Downplayed with Dede. She still remains icy but she does learn a bit about the value of family. [[spoiler: It's left open whether or not she goes back to keep her child]].
* TheDitz: Matt. When Dede tells him she's late, he assumes she's talking about school.
* DoWrongRight: Bill catches a student writing an insulting statement about him on the bathroom wall. He makes the kid correct the grammar, then lets him go.
* ExpositoryHairstyleChange: Lucia's shorter hair at the end of the film symbolises [[spoiler: her happy new life as Carl's wife and a mother]]. Meanwhile Dede's shoulder length hair grows out to waist length suggesting [[spoiler: she might keep her kid after all]].
* FagHag: Lucia still hangs out with her deceased brother's boyfriend.
* FlamboyantGay: Jason. And how.
* GoryDiscretionShot: When the gun is fired in the hotel room. It leaves us in doubt whether Randy or Dede gets shot.
* HardDrinkingPartyGirl: Dede is a pretty dark example.
* KarmaHoudini: Jason. He gets Bill suspended from his job after cooking up a sexual abuse story and he ends up getting the guy at the end.
* LettingHerHairDown: Lucia after [[spoiler: she and Carl have sex]].
* MaybeEverAfter: A non-romantic example. It's left open whether or not Dede [[spoiler: decides to stay with her baby]].
* PlayingAgainstType: Both the female leads. Ricci was known for playing definitely more family-friendly adolescents and Kudrow was known as [[{{Friends}} a certain airhead from New York]]...
* PosthumousNarrator: [[spoiler: Subverted as Dede allows the audience to believe she dies twice in the film]].
* SkewedPriorities: Lampshaded by Lucia after Matt suggests getting married due to Dede's pregnancy.
--> '''Dede:''' I just don't think we should rush into it.
--> '''Lucia:''' No but 'bring another life into the world', that's whim time.
* StraightGay: Bill.
* NoBisexuals: Lucia certainly has this attitude. When Matt tries to explain he's bisexual, she remarks "I went to a Bar Mitzvah once, that doesn't make me Jewish."
* TheTwink: Jason.
* UnreliableNarrator: Dede. She even lets the audience think she dies twice. [[FirstPersonSmartass And berates the viewer for believing her]].
* WalkingShirtlessScene: Matt
* WouldHitAGirl: Randy gets into a literal fight with Dede in the hotel.
** Especially notable since (bitchy or not), Dede is at least seven months pregnant when it happens.
