nut graf:
The term "snowflake" has been used to refer to children raised by their parents in ways that give them an inflated sense of their own uniqueness.[3][4][5] This usage of "snowflake" may originate from Chuck Palahniuk's 1996 novel Fight Club, and its 1999 film adaptation. Both the novel and the film include the line "You are not special. You are not a beautiful and unique snowflake."[4][3][6] In January 2017, Palahniuk claimed credit for coining this usage of "snowflake", adding "Every generation gets offended by different things but my friends who teach in high school tell me that their students are very easily offended"; Palahniuk has called it "a kind of new Victorianism.”[7]
