Something that is of high quality and therefore found attractive by large numbers of people, although often a pseudointellectual minority insists it is crap. But then they would, wouldn't they. Pure sour grapes.
Take Justin Timberlake for instance. Please, ha ha! No, only kidding. Timberlake is clearly one of the greatest talents of his generation, standing proudly next to the likes of Michael Jackson, and Rolf Harris; otherwise why would so many mentally stable people buy his records!?? It's just common sense really.
