word patterns

Been thinking about the ways in which patterns exist in society. For example, the integration of complicated words into the vocabulary of non-complex thinkers. I'm not trying to be a snob, it's just interesting. For example, I heard one girl walking down the hallway, and she said "Yeah, I have to get the interior refurbished." I doubt this girl has ever used the word refurbished in her life - but it has been so integrated into car talk that she just used it without thinking. Can't think of any other examples right now
