"The Backstreet Boys were so ten years ago. Whatever"

Paris Hilton's quote implies that the Backstreet Boys, a popular young boy band from the late 1990s and early 2000s, are no longer appropriate. She is suggesting that their music and fame have actually become out-of-date which they are no longer popular. This might be analyzed as an indication of the times, as patterns and popular culture are continuously changing. It might also be seen as an indication of her own individual taste, as she may not be a fan of the Backstreet Boys' music. Her usage of the word "whatever" might be seen as dismissive, as if she is not interested in talking about the subject even more. In General, Paris Hilton's quote suggests that the Backstreet Boys are no longer pertinent which their music is obsoleted.
