刚刚查了一个短语，维基页面说：
Mumbo jumbo, or mumbo-jumbo, is 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."
用我的话来说，就是有点瞧不起地、以幽默讽刺的方式指代专业术语或行话。
