What is the author's style in High Fidelity by Nick Hornby?

Hornby uses an informal style with many British colloquiums. Non-British readers may find these hard to understand, but as a character, Rob is a product of his environment that of course is Britain and the recession the country went through in the early nineties. Despite this, Hornby also constantly references, and uses as metaphors, American popular culture. The references work in two ways. First, they highlight how he hides from his real feelings, and second, they mark the conflict Britain has with the older generation who are more interested in British values and the younger generation who want to move on.
