Comes from the october, 2009 incident where Conan O'brien fell hitting the back of his head as he was performing a skit with guest Terri Hatcher. A few days later, Jay Leno Pulled a Conan by banging his head during the taping of a show. He did say, however, that he would've rather Pulled a Letterman.

A portmanteau of carpe diem, a Latin phrase that means “Seize the Day!” and DM, which stands for Direct Messages. This word means seizing the day via DMs.
