Between "as if" and "totally buggin'," the teen talk in Clueless is legendary. Not only did Heckerling infamously sit in high school classes in Beverly Hills, but she also read a slang dictionary (before the days of Urban Dictionary) to spice up the teen vernacular in the movie. In a chat with Interview, the director noted, "I read one slang dictionary . . . this was before you could find anything online. I think that had the Baldwins and the Monets. An actor came in and said 'aggro,' and he said, 'Can I say 'postal?' I went, 'Sure.' It seemed like such a great descriptive word."
