Syntax and Diction: Kerouac

They danced down the streets like dingledodies, and I shambled after as I've been doing all my life after people who interest me, because the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones that never yawn or say a commonplace thing, but burn, burn, burn...
- Jack Kerouac, On the Road, Part 1, Ch. 1

It is a renegade sentence with made up words and grammar violations about living a renegade life, violating norms of society, choosing the path of following passion, "burn, burn, burn" rather than anything "commonplace". It is a jazzy, discursive, proud sentence--both its structure and its content.   By saying that "the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved..." the writer signifies disdain for those who follow the well-trod path of conformity. This sentence makes you want to dance down the street like a dingledody.
