Have you ever met a Schrodinger's "Jerk"? What's your story and when did you realize they were one?

Schrodinger's "jerk":
A person who decides whether or not they're full of shit by the reactions of those around them.
Example: John often says racist, homophobic, sexist, or rude things to people. If he's called out on it he says "I was joking" but if he isn't he says nothing. He's a real Schrodinger's jerk.
