The Girl Next Door is actually a very romantic comedy from 2004, despite it's porn-ish premise. It is a reference to the girl all teenage boys wished lived next door. A seriously hot girl. That looks like Elisha Cuthbert.
Eli: Matthew, I tell you that you're going to regret this. What would JFK do? You know he'd tap that ass. Matthew: Eli, you're never going to see her again. Eli: Oh, you know what? Fine! Matthew: Fine! Eli: Fine! Goddammit Matt! I swear to God if you don't fuck her, I'll kill myself! Matt! Please! Please! Matt! Fuck her for me! For me!
Eli: Dude, don't mess this up. Matthew: Mess what up? Eli: Matt, she's a porn star! Okay? Take her to a motel room and bang her like a beast! Matthew: Eli, I like this girl. Eli: And you can still like her with your penis inside her.
