Bachelors and lifelong best friends, John Beckwith (Owen Wilson) and Jeremy Grey (Creator/VinceVaughn) are partners at a law firm in Washington D.C. who frequently "crash" wedding parties to meet women; working from a set of rules taught to them by a past "crasher", the duo always have cover stories for inquisitive guests and inevitably become the hit of every reception -- all so they can charm their way into bed with ladies at the wedding for a one night stand.

After a sequence of successful "crashes," Jeremy spots the wedding of the daughter of the Secretary of the Treasury William Cleary (Creator/ChristopherWalken) and his wife, Kathleen. After infiltrating the lavish event as brothers, John and Jeremy set their sights on two bridesmaids, also daughters of Secretary Cleary: Claire (RachelMcAdams) and Gloria Cleary (IslaFisher). This 2005 film is the very definition of...[[ExactlyWhatItSaysOnTheTin you know.]]

-----
!!!Tropes available:
* BastardGirlfriend: Gloria has the perfect way of getting her man: first scare the shit out of him by acting crazy, then tie him up against his will and rape him. Of course he eventually learns to like it, and their relationship [[HollywoodMasochism seamlessly develops]] into [[CasualKink normal roleplaying]].
* BitchInSheepsClothing: Sack Lodge, at least to Claire and her family.
* TheBigGuy: Throughout the movie a number of references are made to Vince Vaughn's (and thus Jeremy's) large size.
-->'''Jeremy''': C'mere, let the big bear put his paws on ya!
* BitterWeddingSpeech: John does one during a montage.
* BlondeBrunetteRedhead: The Cleary sisters
* BlueBlood: Oh so much, but see the archetypical WASP-y looking Creator/BradleyCooper as "Sack" Lodge for your best example.
* BrokenPedestal: [[spoiler:John and Jeremy are quite disappointed when they finally meet Chazz, and discover he's a pathetic manchild BasementDweller.]]
* TheBrute: Sack Lodge practically embodies this trope.
* TheCameo: [[spoiler: [[CrowningMomentOfFunny Will Ferrell as Chazz]].]]
** Also a OneSceneWonder.
** Also John [=McCain=] AsHimself.
** Same with James Carville.
* CastingGag: ChristopherWalken and Jane Seymour were the Bond villain and Bond girl from Roger Moore's [[Film/AViewToAKill last]] and [[Film/LiveAndLetDie first]] Film/JamesBond films, respectively.
* DepravedHomosexual: Todd.
* DisposableFiance: The EvilAllAlong category. A better use of the trope than in some other romantic comedies, in that while Sack is a {{Jerkass}}, he is also charming and charismatic enough that it isn't a complete mystery that Claire is dating him in the first place.
* DoubleStandardRapeFemaleOnMale : ''Gloria ties Jeremy to the bed and forces herself on him.'' The morning after, he tells John that he "...felt like JodieFoster in ''Film/TheAccused''. He ultimately falls in love and marries her.
* DoubleStandardRapeMaleOnMale: Immediately after the incident above, Gloria's gay brother attempts to force himself on the still-restrained Jeremy. Jeremy finds this situation horrific instead of ultimately endearing as he had with Gloria.
* FanserviceExtra: The absurdly beautiful Diora Baird and all the other actresses that flop down on beds with Vince and Owen in the sex montage.
** Isla Fisher's body double. That scene is also an example of BlackComedyRape.
* TheFunInFuneral: The protagonists' mentor, Chazz, (played by [[spoiler: Will Ferrell]]) eventually replaced "getting women at weddings" with "getting women at funerals". And he brings John along for a demonstration. It is this practice that qualifies as his MoralEventHorizon.
* GirlOnGirlIsHot: Jeremy's girlfriend, Gloria, asks if he wants to watch her do it with a Brazilian girl. He proposes.
* HorribleJudgeOfCharacter: Claire and her family when it comes to Sack.
** [[SubvertedTrope Subverted]] with William Cleary. At the end of the film he was shown to be aware of Sack's {{Jerkass}} traits, but was willing to turn a blind eye as long as he was making his daughter happy.
* HugeGuyTinyGirl: Jeremy and Gloria, as with any actress who gets paired with Vince Vaughn as a romantic lead.
* {{Jerkass}}[=/=]JerkJock: Sack, big time.
* KarmaHoudini: Sure, Sack gets punched in the face and Claire dumps him at the end, but he never gets exposed for cheating on her.
* KickThemWhileTheyAreDown: Sack Lodge repeatedly tackling Jeremy ''very'' hard during a casual game of football (it is clearly stated to be a game of ''touch'' football, where such tackles are not meant to be used), without second thoughts of how badly hurt the latter may be. Sack's followers even rub it in Jeremy's face, saying "That's what we call [[{{Pun}} a sack lunch]]!"
* LaxativePrank: John does this to Sack.
* LonersAreFreaks: Todd.
* ManipulativeBastard: Sack Lodge.
* NaughtyUnderTheTable: Gloria gropes Jeremy under the dinner table.
* ThePublicDomainChannel: What [[spoiler: Will Ferrell's]] character is watching in his first scene.
* RacistGrandma: The grandmother loves saying inappropriate things about Eleanor Roosevelt.
* RomanticComedy
* SevenMinuteLull: When Jeremy is talking about his "first Asian".
* SexMontage
* SexualKarma
* SmugSnake: Sack Lodge.
* TheSociopath: Sack Lodge.
* SpeakNowOrForeverHoldYourPeace: John does this.
* StalkerWithACrush: Gloria.
** John even more blatantly.
* TestingTheLoveInterest: Claire does this later in the film.
* TheUnapologetic: Jeremy had made a foul remark about one of the proper ladies in the wedding, earning him the glares from the guests. He then claims this statement to John:
-->'''Jeremy''': I'm sorry. I'm not sorry. Okay? I'm not gonna apologize, I'm a cocksman! *gets glares from wedding guests again* Tourette's.
* UnsympatheticComedyProtagonist: Jack and Jeremy, oddly enough. A lot of the humor in this movie would be very uncomfortable, except for one thing: the main characters are philandering serial liars until they get a little CharacterDevelopment forced on them, so who cares what happens to them?
* WhatDoesSheSeeInHim: Claire and Sack. Sure, he's played by the muscular Bradley Cooper, but he is one of the most over the top assholes in cinematic history.
** As Roger Ebert put it in his review, "in a comedy the villain is supposed to be [[LaughablyEvil funny]], and not a hateful, sadistic, egotistical monster".
** It's implied to be just a relationship of convenience more than anything else.
* {{Yandere}}: Gloria.
