Need Help Figuring Out What Movie This Is??

[CZAR]

Ok the movie goes something like this: 2 teenage girls either start crank calling people or doing something by phone, they eventually start talkin this older guy. The girl pretends to be her mom and even sets up to go out on a date with this guy. But for whatever reason the girls think its a joke or whatever. So the night they are suppose to go out. the daughter goes to spend the night at her friends house and leaves the mom home alone. The guy shows up and attacks the mom and events start happening. The girl comes home and starts apologizing to mom for starting being responsible for the man going to the house. Does this ring a bell?? Thanks!! Got Em!!
