What is the author's style in Choke by Chuck Palahniuk?

Palahniuk tells the story in the first person. The narrator and main character is the self-hating sex addict Victor Mancini. His account of his life is so over the top, the reader never doubts its unreliability. In fact, the exaggeration plays a part in the books humor. Victor is trying to present himself as someone he is not, when in reality the only way he can move on is by accepting who he is. The reader also knows Victor's account is unreliable because he often contradicts himself. For example, throughout the book he claims his mother is a crazy, deluded eccentric, responsible for all of his problems. However, when Victor overhears a conversation she has with Dr. Marshall, she appears sane and articulate.
