non porn scene

I am looking for a non porn movie, maybe some one can help. all I can remember is a man and woman are have sex in a big hotel bathroom, he picks her up, she wrap her legs around him. he goes to put her against wall but is a hook he done not know about it goes thought her head and kills her instead of calling the cops the guy and his friends chop her up and put her in a suitcase I know it' a long shot but if any one can help thanks

Well if it's a movie starring Cameron Diaz and Christian Slater where the body count mounts up on a pre-wedding "Stag-weekend" in Vegas then it might be "Very Bad Things"

Definitely Very Bad Things; great dark comedy.

wow I did not think any one would be able to help. thanks guys
