A: Did you read this book the teacher asked us to read?

B: Yes, I found it quiet interesting.

C: No. What’s all this mumbo jumbo? I can’t even finish reading the preface.

Note: Mumbo jumbo, or mumbo-jumbo, means confusing or meaningless language. The phrase is often used to express humorous criticism of middle-management, and specialty jargon, such as legalese, that non - specialists have difficulty in understanding. For example, “I don’t understand all that legal mumbo jumbo in the fine print.”
