Scenario: Someone publicly says, "We have made a decision" in reference to an important choice, but no matter how many people ask what the decision was, the person does not say. Later, when asked about why they refused to disclose what their decision was they reply with "Because I don't want everyone to know."
Question: Is there a word that conveys 'keeping someone wondering purposely' or describes a type of person who does?
Note: I am aware that a**hole fits nicely as an answer, but I'm looking for something a tad classier.
Martin Luther King publicly saying "I have a dream" and then thanking everyone for being so supportive of him without telling them what his dream is.
Or a person who asks if you want to hear a joke, then says "a guy walks into a bar" and then leaves without telling the punch line.
