This was a movie that I had seen as a youngster, when I was around the age of twelve. The story was about a bunch of older teenagers (a lot older than me at the time) that got their kicks by "crashing" parties, in other words, upsetting others' enjoyment for their own personal satisfaction. Not to divulge, but I will say they finally crashed a party run by people old enough to be their parents, or by folks that knew how to really have a good time (for themselves). All of a sudden, the "crashers" seemed to behave like little elflings... It's a true reflection on behavior. Nothing has changed... this movie still makes a lot of social sense. Try to find it.
