Generican

The generic American accent Australian film and TV actors learn, making them conspicuously foreign against their native American co-stars. Having no obvious dialectic influence from any particular state or region results in them learning a US from what they've heard on TV and film, thus perpetuating the Generican accent as its own "Springfield" of American accents.

It's so distracting hearing Russell Crowe's generican accent every time he has a line. Where the hell is his character supposed to be from?
