Common Sense Note
Parents need to know that this R-rated comedy is much crasser than star Katherine Heigl's last romcom, 27 Dresses. It's heavy on sexual references and scenarios (Jell-O wrestling, vibrating underwear, etc.) and light on sweetness. The characters are stereotypes until the end, and most of the messages about dating and relationships are shallow and, frankly, sexist (i.e. women should play games and hide all traces of their true personality if they want to "land" a man). There's also lots of strong language, from swear words like "f--k" and "s--t" to body-part terms like "balls," "c--k," "p---y," and "tits."
Sexual
Content
Although the movie is more talk than action, there's a lot of talk, with frequent use of sexual/body part words and euphemisms like "balls," "p---y," "tits," "blow job," "funbags," etc. and frank discussions about sex and attraction. After discussing masturbation with a male co-worker, a woman dons vibrating underwear and has an orgasm during a business dinner. Two other women wrestle in a vat of Jell-O in bikinis. There's also a brief shot of partial nudity (a naked man is shown from the back from the waist down), plus some passionate kissing and one scene with implied sex (including lots of noises).
Violence
Abby almost falls out of a tree and needs rescuing; lots of verbal sparring, with some yelling.
Language
Frequent use of everything from "f--k," "s--t," "p---y," and "c--k" to "crap," "hell," "goddamn," "oh my God," "bitch," and more.
Social
Behavior
Although in the end the main characters learn that it's being yourself that matters, most of the movie revolves around sexist, stereotypical ideas of how a woman should act if she wants to "land" a man -- and how not to act if she doesn't want to scare them all away forever (it basically boils down to playing games and hiding all signs of your true personality...). Other choice bits of advice include never criticizing, laughing at all of a guy's jokes, being sexy but also aloof, etc.
Consumerism
Pretty subtle placement of logos for a few products (BMW, for instance).
Drugs / Tobacco /
Alcohol
Some social drinking (wine, mixed drinks), but the characters are all adults, and no one appears to overindulge.
