I'm looking for a movie I only vaguely remember one scene from. There's a kid and his family all together, possibly in celebration of something, when suddenly people break into their house. They start getting violent and at one point one of them rips the kid's pants open and rapes him, and his inner narration is "I thought it only happened to girls" or something like that. It was a very long time ago that I saw it, at the very least 10 years ago.
