What is the title of the movie where there is some girl who chugs a gallon of milk and then throws up in the gallon before drinking it again. She keeps repeating this. I believe it is a horror movie but can't remember what movie it was and it's really bothering me. Please help!

I think you're talking about the exorcism of emily rose

It took a bit for it to come in mind.

The Grudge 2 (2006)

http://www.imdb.com/title/tt0433386/

From Parents' Guide:

A teenage girl drinks a lot of milk from a bottle then gags and spits it back into the bottle.

Here's the scene on YouTube:

Thank you!

Thank you!

You're welcome! I initially thought it was the third film, then it flashed into my mind that it was the first sequel. What a bizarre scene!
