Identify a Horror Movie!!
 

I cannot think of the name of this movie!! Please help.

A couple goes to like a vacation house in the Hamptons or some place, and while there these 3 Super Preppie kids,(2 Boys and a Girls I think), But they are dressed in like all white, and they terrorize the couple, beat him with a Golf Club, rape his wife and cut her throat while she is tied to a chair, whil they made him watch on the couch. They are super polite kids but psychotic.

Please help me figure this out. It's been killing me.

It sounds like it could be either Funny Games or The Strangers.

Yea, pretty certain its Funny Games...

Funny games!!!!!
 

Thank you guys soooo much. I was going nucking futs trying to figure it out.
