I saw this movie last night. I just had to see how bad it was. I was actually surprised at how NOT bad it is. Don't get me wrong, it's not very good either, but it's not as cringe-worthy as it sounds. To be honest the biggest stretch in the whole thing was the circumstances in which someone would commit murder. I guess they figured once one person is dead anyone is willing to kill.
Basically the donkey punch is brought up during some idle chatter about dirty sanchez and other sexual acts, but with the general attitude of it being taboo. Really? You can talk about a dirty sanchez, but when someone says donkey punch, it's "really man, there's ladies present." So then when 3 guys and 2 girls decide to have an orgy in the bedroom, a younger and less experienced guy takes "do her harder" and "you're about to come? You know what to do" to mean he should donkey punch her, and of course he breaks her neck.
Really, aside from what I've mentioned, it all seems relatively believable. Well, except the part where 3 girls go out to sea on a yacht with 4 guys they just met. Or maybe I'm running the the wrong (right?) circles of friends.
Don't get me wrong. The movie is not good. It's just not THAT bad.
