The road to the movie's "lesson" is hilarious and often raunchy, but the message is earnest: Good friendships don't come often, so cherish them. And also this: Your life is what you make of it. So if you're down, get on your feet.
A woman goes berserk at a bridal shower and attacks the decorations and the cake and upends tables. A medicated airplane passenger causes a commotion that drives a federal marshal to action. Some discussion about where to stash a gun.
The movie opens with an energetic, often loud sex scene; no sensitive body parts are shown, but nudity is implied (you can see down the whole side of the man's body at one point), and the woman is wearing a bra and underwear. Lots of moaning and groaning. A man squeezes a woman's breast through her bra and talks about having "f--k buddies." A couple is shown making out and trying to rip each other's clothes off; later, she wakes up in bed covered by a sheet (nudity is implied). Another character propositions strangers, sometimes crudely. A woman takes off her top to get a man's attention (shoulders shown, but not breasts). Plenty of sexual innuendo/talk; a woman does an impression of a penis.
Strong, frequent language includes "f--k" (and many permutations of it), "s--t," "d--k," "c--k," "c--t," "ass," "a--hole," "goddamn," "damn," "oh my God," "hell," and more.
Some glimpses of labels, but the bigger issue here is the commercialization of weddings and the "bigger is better" ethos that has pervaded the whole engagement-to-nuptials journey.
Drinking, Drugs & Smoking
Lots of champagne- and wine-swilling at events, sometimes to excess. A woman gives a friend prescription drugs to calm her nerves during a flight, which she combines with hard alcohol -- to detrimental effect.
