You can't. It is not recommended to use the word "academic rubbish" in the thank-you part of academic papers, because it will be regarded as impolite or inappropriate language, and may arouse the resentment of reviewers or readers. When writing academic papers, acknowledgements are usually used to express the author's gratitude for the support and help received by the research, as well as the support provided by data, technology and equipment. In short, thanks should be true, objective and sincere, and should follow academic norms and good academic etiquette.
