To "make a fool" out of yourself means to make yourself look foolish or stupid. When you make others look like a fool, it means that you've tricked or deceived them in a way that caused them to act or look foolish. Ex: He cheated on me, making a fool out of me in the process. Ex: The jokester made a fool out of the victims of his prank.
