The belief of sales, marketing, and advertising professionals that the Millennial demographic represents a completely unique group of consumers and as such, entirely new approaches must be adopted. Even if the product you are trying to sell is intended for a completely different demographic, such as Depends Adult diapers.
I tried to explain to the Creative Director that the hipster didn't represent our customer demographic, but she's got a bad case of millennialitis.
