You do like that girl, don't you? Answer: No! I don't! Not at all! Why do you think so? Reply: You protest too much. #Protest too much comes from Hamlet by William Shakespeare; the Queen speaking: The lady doth protest too much, methinks. (Note: people do not usually use the word methinks when they are speaking English today.) To protest too much is to insist so passionately about something not being true that people suspect the opposite of what you are saying.
