Dear Evan Hansen is a stage musical that premiered in Washington DC in 2015 before opening on Broadway in 2016. In the song Sincerely Me, Evan Hansen and Jared Kleinman invent cheerful emails from Connor Murphy, and Jared throws in the word kinky as a cheeky aside while they rewrite the messages. Fans clipped that single word because Jared's delivery captures his sarcastic, teasing personality in under a second. The isolated line spread in theatre fandom edits and reaction posts as a quick shorthand for playful embarrassment.
