In English you teach someone how to say their name by saying: My name is ''blah blah'' or My name is ''whatever''. Your voice drops on the words blah blah and whatever to show that your name is not actually blah blah or whatever and there is a little pause beforehand. I speak Mandarin Chinese and when saying a sentence that requires inputting a certain word you can include 什么什么 which literally means ''なになに'' or ''what what'' but in this context means ''blah blah'' or ''whatever''.
