How does the author use repetition in the novel, The Tin Drum?

Example of Repetition:

"Lobsack had wit. He derived all his wit from his hump, which he called by its name; the crowd always likes that. Before the Communists would be allowed to take over he would lose his hump. It was easy to see that he was not going to lose his hump, that his hump was there to stay. It followed that the hump was right and with it the Party - whence it can be inferred that a hump is an ideal basis for an idea."
