Parents, this your comedy craving teens will be dying to see this hilarious finale to "The Hangover", but the mature content makes this irresistible ending for only the most mature teens out there. This last installment doesn't have as much sexual content as the first two, but has the heaviest violence and language, along with strong drug material. Sexuality includes flirting, kissing, some sex talk, a brief sex scene involving a lollipop, scantily clad women that may possibly be topless, masturbation with no nudity, one character is a retired stripper, and a character imitates ejaculation. There is also one scene with graphic nudity (buttocks, genitals, nipples, breasts, lingerie, sex toys). Drug and alcohol use includes coicane references, meth use, drunkenness, and one character dies from alcohol poisoning. Violence is mostly cartoonish in the first two parts, but there is nothing bugs bunny-ish about this. It includes a harrowing kidnapping, torture, physical threats, homicide involving gangsters, animal cruelty, drugged abduction, punching, people falling off buildings and carjacking. The language is also constant and pervasive. Usage of swearing includes f--k, s--t, w---e, c--t, c--k, p---y, d--k, a--hole, b--ch, m-therf--ker, and b--w j--.There are derogatory/racist terms used too. I would rate this movie R For Strong Sexuality, Graphic Nudity, Drug Use, Pervasive Language Including Derogatory & Racist Terms Throughout, Brief Violence Involving Brutal Disturbing Images & Mayhem, and that anyone but the most mature teens should not watch.
