My girlfriend and I threw a dinner party a month ago and one of our guests asked the group: "Who is your celebrity nemesis?"
Since then, I've been dropping this little conversational prompt whenever there's a silence that needs to be filled or a vibe that needs livening. It's so much more interesting than asking someone their celebrity hall pass, and it's a great way to indulge your inner hater without hurting anyone's feelings.
For the record: my celebrity nemesis is Lin Manuel-Miranda.
