Though this comedy ends on a "BFFs forever!" note, with the characters clearly headed into happy futures, that doesn't change the fact that most of the rest of the story was filled with death and mayhem. Some jokes at larger characters' expense.
Three characters die/are killed; one of the deaths is abrupt and shocking and leads to pools of blood and a body-disposal problem. Another is bludgeoned in the face by a heavy sculpture (in self-defense), and another is hit by a car. At no time does anyone express grief for the loss of life or the impact on the dead characters' loved ones; the deaths barely seem to matter (because the characters are criminals?) and are called "good murder" at the movie's end. A dead body is shown at great length, participating in various ridiculous scenes: propped up in a leather sex swing with a silly mask on, kissed on a beach by a woman trying to pretend he's alive, etc. Violence is frequently played for laughs -- as in scenes in which a dead man catapults out of the top of a car's sunroof.
One character participates in a three-way with a horny couple in order to shore up an alibi; she's depicted receiving oral sex from the woman with her legs in the air, shrieking (the other woman's body covers her private parts). The main characters are on a bachelorette weekend, so penises are everywhere: penis straws, penis pasta, a Groucho mask with a penis nose that appears on the face of a dead man, etc. One partygoer explains that the women will be "swimming in d--k." An extended sequence features a man wearing adult diapers on a road trip. Jokes reference infidelity, sexually transmitted diseases, sex toys, sexual fetishes, picking up strangers at gas stations to pay them for sex acts, and other mature topics.
Frequent strong language includes "f--k," "motherf-----r," "hell," "damn," "bitch," "c--t," "ass," "a--hole," "d--k," "p---y," "dips--t," etc.
Frequently visible brands/products include liquor, cars, and phones.
Drinking, Drugs & Smoking
Characters are out to party/get wasted and consume huge amounts of liquor, screaming "shots!" and trying to get as drunk as they can. They also smoke pot (in an apple bong) and repeatedly snort cocaine. A man who has to make a long car ride is given "expired" prescription pep pills from a foreign country to stay awake; he also plays a middleman for a methamphetamine purchase.
