How do you play THAT game?

My coworker Diane called me at the reference desk with an idea for an icebreaker activity for the online class we will be teaching this winter. An icebreaker activity helps students get to know each other at the beginning of a course. She said the game was called "Name that cowlick." Say what? How do you play that? I wondered briefly before asking her to repeat what she said. This time I got it right: Name that colleague. Tee hee. I think my version sounds like more fun.
