Amid the raunchy humor is the message that friends and couples need to make the effort to maintain relationships, whether it's the occasional night out with the guys or scheduling time for a husband and wife to be alone without the kids.

Several people get into a drunken brawl outside a party, with plenty of punches, kicks, and knock-down, drag-out fighting. Some couples get into heated arguments.

Male and female nudity, including bare breasts, male backsides, and an extended look at one man's penis. Several sex scenes include vigorous thrusting and suggestions of oral sex, given by both genders. Both men and women are interrupted masturbating, and there's a not-so-brief look at online porn (with sound effects). Plus nearly constant talk about sex -- who's having it, who isn't, who wants to, and how -- usually in the crudest possible terms.

Every possible swear word -- from "f--k" to "s--t" to "p---y" and more (including "c--k," "d--k," "ass," "hell," "oh my God," and more) -- is used, multiple times and often in creative permutations.

Apple products make an appearance, as do Chevy cars and online retailer Amazon.

Anywhere the crowd is gathering, there's plenty of drink, including beer, shots, wine and hard liquor. Several scenes feature underage drinking, including a long sequence in which a very drunk high school girl celebrates her 18th birthday. One woman lights up a joint, and another group passes around a bong at a party.
